Ethyl xanthate is an excellent collector for sulfide minerals such as copper, lead, zinc, molybdenum, and nickel. Xanthate is the best collector for sulfide copper. It also has a certain foaming property, suitable for acidic or alkaline pulp. On one hand, xanthate is an excellent collector for sulfide copper, and the sodium thioglycolate recovered from the tailings is the best non-toxic depressant for sulfide copper, which can replace cyanide without the need for an activator, and sulfide copper can be selected with xanthate. This has made a significant contribution to the environmental protection of mines and the improvement of economic benefits. Specifications: 25kg.
