[0001] This utility model relates to the field of mineral processing technology, and in particular to a device for improving the recovery rate of associated gold and silver through low-alkalinity copper-sulfur preferential flotation. Background Technology

[0002] The low-alkalinity copper-sulfur preferential flotation device for improving the recovery rate of associated gold and silver is used in the mineral processing field. It is used to separate ores containing multiple valuable components such as copper, sulfur, and associated gold and silver through flotation to improve the grade of copper concentrate, the recovery rate of sulfur concentrate, and the recovery rate of associated gold and silver. The low-alkalinity copper-sulfur preferential flotation device is suitable for the beneficiation of polymetallic ores containing copper, sulfur, and associated gold and silver. Through copper-sulfur separation and reagent control in a low-alkalinity environment, the copper concentrate grade, sulfur recovery rate, and associated gold and silver recovery rate are simultaneously improved.

[0003] When workers need to process ground minerals, they pour the minerals into the equipment and add the relevant reagents so that the equipment can process the minerals. However, existing equipment may experience coarse mineral sedimentation during use, causing some minerals to form dead ore at the bottom of the equipment, which in turn reduces the equipment's recovery efficiency for the target minerals. Utility Model Content

[0006] Preferably, the surface of the support plate is provided with a heating device, the heating device including a placement groove, the placement groove being formed on the upper surface of the support plate, the upper surface of the support plate having a slot, the slot communicating with the placement groove, the above components working together can achieve the purpose of storing the heating tube, the placement groove can store the heating tube, and the slot can store the conductive sheet.

[0007] Preferably, a heating tube is placed inside the placement groove, and a support plate is fixedly connected to the outer surface of the heating tube. The support plate is placed on the upper surface of the support plate. The heating tube can be supported by the cooperation of the above components.

[0008] Preferably, a positioning rod is inserted and connected inside the support plate, and the positioning rod is threadedly connected to the inside of the support plate. The above components work together to achieve the purpose of stabilizing the heating tube. The positioning rod, the support plate, and the support plate work together to restrict the positioning rod.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, by setting up a lifting device, when the operator needs to improve the recovery efficiency of the device for minerals, the drive motor is started. The operator adjusts the rotation of the conveyor rod according to actual needs. The conveyor rod adjusts the slider, the slider drives the support plate, the support plate drives the slide bar, the slide bar slides and is guided by the guide rod, and the support plate drives the agitator to rise or fall. When the agitator falls, the agitator will approach the dead minerals at the bottom of the flotation machine. The agitator enhances the turbulence intensity of the bottom slurry, prevents coarse particles from settling, and increases the probability of collision between coarse minerals and bubbles. When the operator adjusts the agitator to rise, the agitator reduces the bottom shear intensity, reduces the excessive crushing of fine minerals, and maintains bubble dispersion through gentler stirring in the upper layer. By setting up the lifting device, it is possible to effectively facilitate the operator to improve the recovery efficiency of the device for minerals, avoid the situation where some minerals form dead minerals at the bottom of the device, and thus improve the recovery efficiency of the device for the target minerals.

[0012] 2. In this utility model, by setting up a heating device, when the reagent needs to react rapidly in a low-temperature environment, the operator inserts the heating tube into the placement grooves on both sides of the support plate. The heating tube drives the support plate, which is then placed on the support plate. The operator inserts the positioning rod into the support plate and rotates the positioning rod, which is threadedly connected to the slot on the surface of the support plate. When the heating tube and the conductive plate come into contact with the slurry, the operator transmits electricity to the heating wire through a wire. The heating wire heats up, and the heating tube and the conductive plate transfer the heat to the slurry, causing the temperature of the slurry to rise. By setting up the heating device, it is possible to effectively facilitate the rapid reaction of the reagent in a low-temperature environment, avoiding the situation where the reagent is difficult to dissolve in water, thereby improving the recovery efficiency of the device for the target mineral.

The bottom of the container forms a dead ore deposit, thereby improving the device's recovery efficiency for the target mineral. Furthermore, by setting up a heating device 4, when the reagent needs to react rapidly at low temperatures, the operator inserts the heating pipe 45 into the placement slots 48 on both sides of the support plate 32.

The operator inserts the positioning rod 46 into the support plate 42 and rotates the positioning rod 46, which is threaded into the slot on the surface of the support plate 32. When the heating pipe 45 and the conductive plate 43 come into contact with the slurry, the operator transmits electricity to the heating wire 44 through the wire 41. The heating wire 44 heats up, and the heating pipe 45 and the conductive plate 43 transfer the heat to the slurry, raising its temperature. By setting up the heating device 4, the reagent can be effectively and quickly reacted at low temperatures, avoiding the reagent's poor water solubility, thus improving the device's recovery efficiency for the target mineral.
