Existing problems: the copper and molybdenum ore has daily processing capacity of 10,000 tons. In the process of copper and molybdenum separation, the use of a large number of sodium thioglycolate as an depressant, which result in high cost of agents, also copper content exceeded in molybdenum concentrate.

    Solution: add patented depressant, use together with sodium thioglycolate.

    Result: reduce the using amount of sodium thioglycolate by 40%, reduce production costs RMB 1 yuan/ ton of ore, copper content in molybdenum concentrate in line with product requirements.
