Floatation separation of galena, sphalerite, and pyrrhotite by combined depressant CCSL
工程科学学报, 2017 The flotation separation of galena, sphalerite, and pyrrhotite was investigated with CCSL as a depressant. Flotation test results show that galena and sphalerite can float but pyrrhotite can barely float with CCSL as a depressant.
