Silver copper ore dressing plant (1)
At present, the dressing stone from two stope, press cake containing copper pyrite ore according to the different nature of the ore, sulfur disseminated copper ore, iron ore, zinc yellow bulk copper three types of flow of the process in three floating mill. The grinding process of the three ores adopts two-stage grinding and two-stage grading, and the overflow enters the flotation. Among them, the copper-containing yellow iron ore and the copper-sulphur ore selected from the copper are all used in a coarse, one-sweep, three-fine flotation process, and lime is used as a pyrite inhibitor, and the free calcium oxide in the pulp reaches 800~. 1000g / m 3 under the butyryl content xanthate, No. 2 oil selected from the group of copper, i.e. tailings sulfur concentrate; processing disseminated ore increased copper sulfur Sulfur job can be selected from the group of copper obtained after sulfur concentrate, tailings discarded . The process and indicators of the crushing and grinding of the two ores are shown in the figure
