Antimony: will China continue to control supply?
Nov 14, 2018 · While Backeberg doesn''t think the project is going to ''rock the boat'' for the antimony market because it is only an intermediary step, it does, however, offer a significant supply of nonChinese antimony products. "The problem is it needs to find supply for the roaster to operate," says Backeberg.
