Nigerian copper mine flotation
The process of copper flotation preferential flotation process is: crushing and screening→grinding and grading→priority flotation copper concentrate→activated flotation other concentrate→concentrated dehydration. The preferential flotation process is divided according to the floatability of the ore. First, a single copper concentrate is floated and the remaining concentrates are suppressed. After the flotation of the copper concentrate is completed, the remaining concentrates are separately activated and floated.
The preferential flotation process of copper mine has the advantages of easy operation, strict control of the dosage of the chemicals and high grade of copper concentrate.

Production Example
The project is located in Nigeria and is a copper ore beneficiation project with a daily output of 1,000 tons. Before the design of the beneficiation plan, the customer mailed the sample to the Hanfa Design Institute. The experts of HanfaDesign Institute conducted the ore dressing test on the ore sample, and summarized the mineral characteristics through the experimental report, and finally decided to select the copper mine priority flotation process. Sorting.
By analyzing the mineral characteristics and the content of different minerals, the beneficiation scheme was finally determined. The copper mine preferential flotation method, that is, the three-stage open-circuit crushing and one-stage grinding process, preferentially float copper to obtain copper concentrate and sulfur concentrate, and then Magnetic separation gives iron concentrates, and finally two stages of dehydration are carried out from copper and sulfur concentrates. The specific operation is as follows:
1. Three-stage open-circuit crushing: crushing by jaw crusher, the crushed product is transported to the cone crusher by belt conveyor for two or three stages of crushing;
2. Grinding classification: the broken minerals enter the lattice ball mill for grinding and grading;
3. Flotation: After stirring by the agitation tank, the slurry enters the JJF type mechanical agitation flotation machine for flotation, and at the same time, the selective collector is added to preferentially float copper to obtain qualified copper concentrate, and then the flotation is obtained.
4. Magnetic separation of tailings: the tailings obtained by flotation are sent to a magnetic separator for sorting to obtain iron concentrate;
5. Dehydration operation: The copper and sulfur concentrate slurry obtained by flotation is transported to a high-efficiency thickener for concentration, and the concentrated bottom stream is filtered and dehydrated by a plate filter press.
