it is an excellent collector for copper sulfide, lead, zinc, molybdenum, nickel and other minerals. thiocarbamate is the best collector of copper sulfide. it is highly effective, non-toxic and has good selectivity, so it is widely used in the world. it also has a certain foaming property, suitable for acid or alkaline pulp.
more importantly, thiamine ester on the one hand is an excellent collector of copper sulfide, and the sodium mercaptoacetic acid recovered from the tail solution is the best non-toxic inhibitor of copper sulfide, can replace the sodium cyanide inhibition of copper without adding activator, thiamine ester can be used for copper selection. this has made a great contribution to the environmental protection of the mine and the improvement of economic benefits.
