Example of copper barite recovery barite (Jiangsu Guanshan Copper Mine)
Mountain View Lishui County, Jiangsu copper mine since the operation, over the years tailings yield of about 90% to 95%, mainly mineral content of the tailings are: siderite ore 54.61%, 9.32% barite, pyrite 3.26% , hematite 1.04%, quartz 30.99%, taking into account the similarity of the ferrite and barite can be similar, the use of strong magnetic separation recovery of siderite and flotation recovery of barite, recovery of barite The flotation process is shown in Figure 1. The test finally obtained a high quality barite concentrate with 95.3% BaSO 4 and a recovery rate of 77.48%.
