组合抑制剂CCSL浮选分离PbS、ZnS与单斜Fe1-x S的研究
Floatation separation of galena, sphalerite, and pyrrhotite by combined depressant CCSL
摘要
Abstract
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. 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. The X-ray photoelectron spectroscopy (XPS), IR spectrum, and Zeta potential analysis results indicate that the interaction of sodium acetate and pyrrhotite is not only physical absorption. The UV spectrum indicates that the decline in floatability of pyrrhotite is due to the hydrophilicity caused by CH3 COO - being stronger than that caused by dixan-thogen, and the xanthate adsorption on pyrrhotite is not prohibited by CH3 COO - . The CH3 COO - reacts not only with pyrrhotite, but also with H + in water as a H-bond, so the pyrrhotite becomes hydrophilic.关键词
