    2016-11-10 · Flotation test results show that galena and sphalerite can float but pyrrhotite can barely float with CCSL as a depressant. The flotation tests also show that galena can be separated efficiently from pyrrhotite, and that sphalerite can be separated on the whole from pyrrhotite, but the separation efficiency of the former is much better.

    Abstract This experimental work on sphalerite flotation investigated the effect on flotation performance of three particle size fractions, namely, coarse (d80 = 100 μm), medium (d80 = 39 μm) and fine (d80 = 15 μm), bubble size distribution, superficial air velocity, and collector dosage. Bubble size distributions were characterized with the image analysis technique.
