Problems solved by technology

Obviously, there is the irrationality of invalid circulation flotation, which leads to the invalid extension of the flotation process, and the invalid increase of reagents and energy consumption
[0008] 2) The trailing indicators are difficult to control
[0009] 3) The quality of concentrate is difficult to stabilize
from figure 1 It can be seen that although the target particle content of all levels of concentrate pulp tends to increase during the process of producing final concentrate pulp, when the grade of raw ore pulp decreases, the grade of concentrate pulp of all levels also decreases. The quantity change, coupled with the ineffective circulation flotation

Embodiment 1

[0044] Embodiment one: A kind of flotation process of whole process open-circuit flotation of concentrate pulp comprising at least two flotation systems

[0045] figure 2 What is shown is a flotation process of full open-circuit flotation of concentrate pulp comprising at least two flotation systems. Wherein the first flotation system 25 is a front flotation system, made up of 1# flotation cell 9, 2# flotation cell 11, 3# flotation cell 13 and 4# flotation cell 15; the second flotation system 26 It is a post-flotation system, consisting of 5# flotation tank 6.

[0046] The course of work of the first flotation system 25 is as follows:

[0047] The inflow ore pulp 23 of the first flotation system can be the raw ore pulp 8 , or a mixed pulp of the raw ore pulp and the tailings pulp 20 of the second flotation system. After the inflow ore pulp 23 of the system enters the first flotation system 25, it is roughed by the 1# flotation cell 9 to produce the concentrate pulp 7 of ...

Embodiment 2

[0052] Embodiment two: A kind of flotation process of open circuit flotation of concentrate pulp including more than three flotation systems, including three flotation systems, wherein, the first flotation system is a front flotation system, which is composed of more than one flotation tank ; The second flotation system is a rear flotation system, which is composed of more than one flotation cell; the third flotation system is a rear flotation system, which is composed of at least one flotation cell; it is characterized in that: the first flotation The system processes the inflow pulp of the first flotation system to produce final tailings pulp and more than one kind of concentrate pulp; the second flotation system processes the inflow pulp of the second flotation system to output system tailings pulp and one The above concentrate pulp; the third flotation system processes the inflow pulp of the third flotation system, and outputs system tailings pulp and final concentrate pu...

Embodiment 3

[0067] Embodiment three:Another kind of flotation process of open-circuit flotation of concentrate slurry including more than three flotation systems

[0068] Figure 4 What is shown is another kind of flotation process of whole process open-circuit flotation of concentrate pulp which includes more than three flotation systems. Its technical principle and working process are basically the same as those in Embodiment 3. The difference is that in the 1# tank concentrate pulp 7, the 2# tank concentrate pulp 10, the 3# tank concentrate pulp 12 and the 4# tank concentrate pulp 14 produced by the first flotation system 25, the 1# tank concentrate pulp The target particle content of the concentrate pulp 7 is close to the final concentrate grade, and is quite different from the grades of the other three concentrate pulps. Therefore, only the other three concentrate pulps are mixed with the tailings pulp in the 7# tank, and they are disposed of as the inflow pulp 24 of the second f...

Abstract

The invention relates to a flotation method and a flotation system of whole-course open circuit floatation for concentrate slurry. The whole-course open circuit floatation means that the concentrate slurry produced in any flotation tank no longer flows into a flotation system where the flotation tank in which the concentrate slurry is produced is arranged, the concentrate slurry flows into a postpositional flotation system in an irreversible flow manner (i.e. a complete single-way forward flow manner), and a choiceness process is finished in at least one postpositional flotation system. The flotation tank at least comprises a flotation tank provided with spiral rotors and/or an ultrasonic device. The concentrate slurry is slurry flowing out above the liquid level in the flotation tank in a mineralized bubble form. In the flotation process of the flotation method, the tail slurry produced in any flotation tank flows out of the flotation tank in which the tail slurry is produced in the irreversible flow manner and flows into the postpositional flotation system of the flotation system for sequentially scavenging until the tail slurry of the system is produced. The invention can overcome the defect of futile cycle flotation for target particles, the flotation time is greatly shortened, and medicine and energy consumption are significantly reduced.

Description

technical field [0001] The invention relates to a mineral flotation method and process, in particular to a flotation method and process for whole-process open-circuit flotation of concentrate pulp, and belongs to the technical field of flotation. Background technique [0002] The well-known flotation method is a flotation process in which the outflow ore pulp is fully closed. In this process, starting from the flotation cell that produces the final tailings slurry, the concentrate slurry produced by each stage of flotation cell must be closed-circuited to flow back to the front flotation cell for enrichment flotation step by step until the final stage of tailings slurry is produced. The final concentrate pulp is produced; starting from the flotation tank that produces the final concentrate pulp, the tailings slurry produced by each flotation tank must be returned to the flotation tank for scavenging in a closed circuit step by step until the output Final tailings slurry. ...
