  • US10005088B2Flotation of sphalerite from mixed base

    The main objective of the invention was to develop a new flotation collector that could eliminate or reduce the amount of copper sulfate used in the flotation of sphalerite. Different series of collectors such as cupferrons, arylhydroxamic acids and amino mercaptans or amino thiols were synthesized and tested. Amino mercaptans/aminothiols were found to be very effective in
