Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a mineral washing line. Background Technology

[0002] Lateritic nickel ore is a loose, clayey aggregate containing oxides of elements such as nickel, iron, magnesium, cobalt, silicon, and aluminum, formed from nickel-bearing olivine bedrock in tropical or subtropical regions through long-term weathering, leaching, dissemination, and alteration. Due to severe oxidation of the iron content, lateritic nickel ore has an overall reddish-brown appearance. Unlike sulfide nickel ore, lateritic nickel ore is a difficult-to-process oxide ore, and nickel cannot be effectively enriched through beneficiation methods; therefore, washing is necessary.

[0003] In the existing ore washing process, laterite nickel ore is washed, separated, and classified into coarse and fine ore slurry to form a coarse raw ore slurry. The coarse raw ore slurry enters a spiral chute to obtain tailings and concentrate. The concentrate enters a first-stage shaking table for screening to obtain first-stage shaking table tailings and first-stage shaking table concentrate. The first-stage shaking table concentrate enters a second-stage shaking table for further selection to obtain second-stage shaking table tailings, second-stage shaking table middlings, and second-stage shaking table concentrate. The second-stage shaking table middlings are ground and then returned to the second-stage shaking table for further selection. The first-stage shaking table tailings and second-stage shaking table tailings are ground and then subjected to magnetic separation.

[0004] In the above-mentioned ore washing process, the slurry between various equipment is mostly transported using additional power sources, resulting in high energy consumption and high production costs.

[0005] Therefore, there is an urgent need for a ore washing line to solve the above problems. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] Figure 1 This diagram shows a ore washing line according to an embodiment of the present invention. Figure 2 A schematic diagram of a ore washing line according to an embodiment of the present invention is shown. (Refer to...) Figure 1 and Figure 2 The ore washing line includes ore washing equipment and ore beneficiation equipment. The ore washing line can realize the pre-processing of ore. In this embodiment, the ore is specifically laterite nickel ore.

[0039] Specifically, the ore washing equipment includes a feeder 1, a washing machine 2, and a scrubbing machine 3, which are connected sequentially in the gravity direction and arranged at progressively decreasing heights. The feeder 1, the washing machine 2, and the scrubbing machine 3 work in sequence to separate gravel and slurry. The mineral processing equipment includes a hydrocyclone 6, a spiral chute 7, a shaking table 8, and a magnetic separator 10, which are connected sequentially in the gravity direction and arranged at progressively decreasing heights. The slurry outlet of the scrubbing machine 3 is connected to the hydrocyclone 6 via a feed pump. The slurry can flow from the scrubbing machine 3, pressurized by the feed pump, to the hydrocyclone 6. Then, the hydrocyclone 6, the shaking table 8, and the magnetic separator 10 work in sequence to gravity separate the ore. By arranging these devices sequentially in the gravity direction according to the ore processing order, the slurry between the devices can flow naturally from the upper devices to the lower devices under gravity, eliminating the need for an additional power source for slurry transportation, reducing the energy consumption for slurry driving in the ore washing line, and lowering the mineral processing operating costs.

[0040] More specifically, in this embodiment, when the mountain is high enough, the washing equipment and the beneficiation equipment are connected sequentially in the direction of gravity and their arrangement height gradually decreases. At laterite nickel ore mining sites, as the laterite nickel ore is mined, a stepped mountain gradually forms around the circumference of the mine pit. In this embodiment, the washing equipment and beneficiation equipment are placed on the stepped mountain, allowing the various devices in the washing equipment and the beneficiation equipment to be arranged in a stepped manner from top to bottom. The slurry can be transported between the devices using the slurry's own gravity, resulting in low cost. Furthermore, this washing line can be directly set up in a stepped manner on the mine according to the mountain's contours, thereby reducing the construction cost of the washing line's frame and thus the overall construction cost.

[0041] It is readily understood that, in this embodiment, the feeder 1 can be a chain plate feeder from the prior art, the washing machine 2 can be a cylindrical washing machine from the prior art, and the scrubbing machine 3 can be a double spiral scrubbing machine from the prior art. Furthermore, the hydrocyclone 6, spiral chute 7, shaking table 8, and magnetic separator 10 can all be existing conventional devices.

[0042] Figure 3 This diagram illustrates a ore washing line according to another embodiment of the present invention. Figure 4 A schematic diagram of a ore washing line according to another embodiment of the present invention is shown. (Refer to...) Figure 3 and Figure 4In another embodiment, the hillside is relatively low, with few steps, insufficient to allow for a straight arrangement of the various devices within the ore washing equipment and the ore beneficiation equipment. In this case, the ore washing equipment and the ore beneficiation equipment are arranged side by side, with the hydrocyclone 6 positioned at a higher height than the scrubbing machine 3. The slurry outlet of the scrubbing machine 3 is connected to the hydrocyclone 6 via a feed pump. With this arrangement, only one feed pump is needed between the scrubbing machine 3 and the hydrocyclone 6 to complete the slurry transport for the entire ore washing line, thus reducing production costs.

[0043] It is understandable that there is no limit to the number of the ore washing equipment and the ore beneficiation equipment; they can be set according to the actual situation.

[0044] Specifically, the ore washing machine 2 has a ore washing inlet, a first ore washing outlet, and a second ore washing outlet. The ore washing inlet is connected to the feeder 1, and the second ore washing outlet is connected to the scrubbing machine 3. The first ore washing outlet can discharge gravel, and the second ore washing outlet can transport the slurry to the scrubbing machine 3.

[0045] More specifically, the ore washing equipment also includes a first conveyor belt 11, which is connected to the first ore washing outlet and is configured to transport gravel.

[0046] In this embodiment, the ore washing machine 2 includes a screen cylinder that rotates around its central axis. The screen cylinder has open ends, one end serving as the ore washing inlet and the other as the first ore washing outlet. The screen holes around the circumference of the screen cylinder form the second ore washing outlet. A feeder 1 is connected to the ore washing inlet. The feeder 1 is located near the top of the hill and connected to a feeding channel on the hill. The feeder 1 is connected to the ore washing inlet to transport ore to the ore washing machine 2. The feeding channel can be used by transport vehicles to directly dump laterite nickel ore into it. In practical use, the dump truck pours the ore into the feed channel, which is connected to the feed end of the feeder 1. The feeder 1 transports the ore to the screen cylinder of the washing machine 2, and then sprays water into the screen cylinder to wash the ore. Gravel with larger particle size cannot pass through the screen holes of the screen cylinder, so it is transported out from the first washing outlet through the first conveyor belt 11. The slurry formed by the ore with smaller particle size and water flows to the second washing outlet and enters the scrubbing machine 3.

[0047] Continue to refer to Figures 1-4 The scrubbing machine 3 has a scrubbing inlet, a first scrubbing outlet, and a second scrubbing outlet. The scrubbing inlet is connected to the washing machine 2, and the second scrubbing outlet is connected to the hydrocyclone 6. The first scrubbing outlet is used to discharge gravel, and the second scrubbing outlet can flow the slurry to the hydrocyclone 6. The particle size of the gravel discharged from the first scrubbing outlet is smaller than that of the gravel discharged from the first washing outlet.

[0048] It should be noted that the gravel size in this embodiment is only a relative concept and does not limit its specific dimensions. In practical applications, setting the aperture of the screen of the ore washing machine 2 to a set value, such as 2cm, can achieve the gravel screening purpose of this embodiment.

[0049] Continue to refer to Figure 1 and Figure 3 After being cleaned by the scrubbing machine 3, the resulting slurry meets the requirements for subsequent mineral processing and can be transported to the hydrocyclone 6 via the feed pump through the second scrubbing outlet, while small-sized gravel is discharged through the first scrubbing outlet. Since a small amount of slurry still adheres to the surface of the small-sized gravel, a linear vibrating screen 4 is installed downstream of the scrubbing machine 3 to avoid waste. The first scrubbing outlet is connected to the feed end of the linear vibrating screen 4 to transport the small-sized gravel to the linear vibrating screen 4 for further cleaning and sorting. The linear vibrating screen 4 has a gravel outlet and a vibrating slurry outlet, which is connected to the hydrocyclone 6, thereby transporting the slurry adhering to the gravel surface to the hydrocyclone 6 for further refining. This arrangement avoids slurry waste. The gravel outlet discharges the gravel from the linear vibrating screen 4.

[0050] Specifically, the ore washing equipment also includes a second conveyor belt 12, which is connected to the gravel outlet and is configured to transport gravel.

[0051] Preferably, the ore washing equipment also includes a mixing tank 5. The feed end of the mixing tank 5 is connected to the second scrubbing outlet and the vibrating slurry outlet of the linear vibrating screen 4, and the slurry outlet of the mixing tank 5 is connected to the hydrocyclone 6.

[0052] The washing machine 2, the scrubbing machine 3, and the linear vibrating screen 4 produce a large number of fine particles in the slurry obtained from the water washing of laterite nickel ore. To prevent these particles from settling at the bottom of the equipment and hindering their delivery to the beneficiation equipment, a mixing tank 5 is also provided. The feed end of the mixing tank 5 is connected to the second outlet of the scrubbing machine and the vibrating slurry outlet of the linear vibrating screen 4. The discharge end of the mixing tank 5 is connected to the hydrocyclone 6 via a feed pump. The slurry after passing through the scrubbing machine 3 and the linear vibrating screen 4 enters the mixing tank 5, where the stirring paddle continuously agitates the slurry, effectively preventing particle deposition. Furthermore, since the processing efficiency of the washing equipment is not the same as that of the beneficiation equipment, the mixing tank 5 also serves as a temporary storage unit for the slurry. The mixing tank 5 allows for control of the slurry flow rate delivered to the beneficiation equipment, ensuring that the slurry is delivered at a reasonable rate.

[0053] Furthermore, in actual production, each piece of equipment may be damaged or require maintenance, affecting the processing efficiency of the entire production line. By setting up the mixing tank 5 to temporarily store the slurry, even if some equipment is damaged or under maintenance, the mixing tank 5 can still hold or transport the slurry, ensuring the continuous operation of the entire ore washing line. Moreover, in actual production, there are multiple ore washing and beneficiation equipment. In this case, the mixing tank 5 can act as a transitional link, that is, the slurry from all ore washing equipment is transported to the mixing tank 5, and the mixing tank 5 then rationally distributes the slurry to each beneficiation equipment, which helps to improve the processing efficiency of the entire ore washing line.

[0054] It should be noted that in this application, "inlet" and "outlet" should be interpreted broadly. For example, the second washing outlet of the washing machine 2 refers to the screen opening of the washing machine 2. Furthermore, the term "connected" should also be interpreted broadly. For example, the connection between the scrubbing inlet of the scrubbing machine 3 and the second washing outlet of the washing machine 2 can mean that the scrubbing inlet of the scrubbing machine 3 and the second washing outlet of the washing machine 2 are connected via a pipe, or that the scrubbing inlet of the scrubbing machine 3 is located below the second washing outlet of the cylindrical washing machine 2, allowing the ore discharged from the second washing outlet of the washing machine 2 to flow directly into the scrubbing inlet of the scrubbing machine 3. All of the above indicate that the inlet of the scrubbing machine 3 is connected to the second washing outlet of the washing machine 2, and are not limited to a physical pipe connection.

[0055] Reference Figure 1 and Figure 3 The shaking table 8 is provided in multiple ways, and the multiple shaking tables 8 are connected and arranged in sequence from top to bottom in the direction of gravity. The multiple shaking tables 8 can process the slurry in sequence.

[0056] Specifically, in this embodiment, the multiple shaking tables 8 are respectively a first-stage shaking table 81 and a second-stage shaking table 82. The first-stage shaking table 81 and the second-stage shaking table 82 are arranged sequentially along the direction of slurry flow. This arrangement can further separate the slurry so that the particle size of the slurry meets the standards of subsequent processes. It should be noted that the above-mentioned shaking table 8 is prior art, and its specific structure and working principle will not be described in detail here.

[0057] In this embodiment, a concentrate pump tank 9 is also provided between the shaking table 8 and the magnetic separator 10.

[0058] In this embodiment, the ore washing line is also equipped with a dewatering and classifying machine (not shown), which is located at the rear end of the magnetic separator 10. The ore material after magnetic separation by the magnetic separator 10 can be transported to the dewatering and classifying machine by water. The function of the dewatering and classifying machine is to dewater the ore material.

[0059] To better understand this application, the following is combined with... Figures 1 to 4 The technical solution of this application is described in detail below:

[0060] The feeder 1, the ore washing machine 2, the scrubbing machine 3, the linear vibrating screen 4, the mixing tank 5, the hydrocyclone 6, the spiral chute 7, the shaking table 8, the concentrate pump tank 9, and the magnetic separator 10 are connected in sequence.

[0061] That is, the feeder 1 is connected to the ore washing inlet, the first ore washing outlet is connected to the first conveyor belt 11, the second ore washing outlet is connected to the scrubbing inlet, the first scrubbing outlet is connected to the feed end of the linear vibrating screen 4, the second scrubbing outlet is connected to the feed end of the mixing tank 5, the gravel outlet of the linear vibrating screen 4 is connected to the second conveyor belt 12, the vibrating slurry outlet of the linear vibrating screen 4 is connected to the feed end of the mixing tank 5, and the slurry outlet of the mixing tank 5 is connected to the hydrocyclone 6 through a feed pump.

[0062] In practical use, the dump truck pours the ore into the feed channel, which is connected to the feed end of the feeder 1. The chain feeder 1 transports the ore from the washing inlet to the cylindrical washing machine 2. The cylindrical washing machine 2 washes and pre-screens the ore. Large gravel is discharged from the first washing outlet and carried away by the first conveyor belt 11, while the slurry is transported from the second washing outlet to the scrubbing machine 3. The scrubbing machine 3 performs secondary washing and screening of the slurry. Small gravel is transported from the first scrubbing outlet to the linear vibrating screen 4 for further washing and screening. The slurry discharged from the second scrubbing outlet is directly transported to the mixing tank 5. The small gravel washed by the linear vibrating screen 4 is conveyed away by the second conveyor belt 12, while the slurry is also transported to the mixing tank 5.

[0063] The mixing tank 5 agitates the slurry to prevent particle sedimentation and sequentially conveys the slurry to the hydrocyclone 6, spiral chute 7, first-stage shaking table, second-stage shaking table, concentrate pump tank 9, and magnetic separator 10 for separation, obtaining slurry that meets the requirements of subsequent processing steps. Finally, the slurry enters the dewatering and classifying machine for dewatering.

[0064] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
