Xinhai provided a full mining industry chain service project for the Yunnan 1000t/d copper mine flotation project. In the early stage, Xinhai conducted mineral processing tests for it, customized the mineral processing process and the overall construction plan of the dressing plant according to the test conditions, and customized suitable mineral processing Device model. Later, Xinhai helped him complete the installation and commissioning of the dressing plant, and participated in the entire project operation and management services.
1000t/d
SF type flotation machine, stirring tank, ball mill, classifier, high-efficiency concentrator, dewatering screen
The process flow includes two sections and one closed-circuit crushing and screening - one section of closed-circuit grinding - copper flotation (one coarse, three sweeps and three fines) - sulfur flotation (one coarse, two sweeps and three fines) - concentrate dehydration - tailings dehydration.

The flotation process in the copper mine flotation option is divided into two stages, respectively It is the copper ore flotation stage and the sulfur flotation stage.
Copper flotation stage: adopt the process flow of one rough, three sweep and three fine. After the crushed material enters the ball mill from the feeder, when the grinding fineness reaches -200 mesh and 75%, it enters the cyclone for classification. The overflow flows into the mixing tank. After adding medicine and stirring, it enters the first coarse, third sweep, and third sweep. Selected copper ore flotation process. The first coarse and third sweep operations are completed by the SF-4 flotation machine, and the third fine selection operation is performed by the SF-2.8 flotation machine. Finish.
Sulfur flotation stage: adopts the process flow of one coarse, two sweeps and three fines. The flotation tailings are lifted from the lifting stirring tank to the high-efficiency stirring tank for dosing and stirring, and then enter the sulfur flotation process of one coarse, two sweeps and three fines. The first roughing and two sweeping operations are completed by the SF-4 type flotation machine, the selection I is completed by the SF-4 type flotation machine, the selection II and III are completed by the SF-2.8 type flotation machine, and the medium ore Return in turn.
In the end, the copper concentrate grade of this copper mine flotation project was 23.00%, the copper concentrate yield was 3.45%, and the copper recovery rate reached 91.21%.
