; flotation separation; depressant; polyaspartic acid 1 Introduction Chalcopyrite (CuFeS2) and sphalerite (ZnS) are the main copper and zinc minerals found in complex sulfide ores, and they are closely...Trans. Nonferrous Met. Soc. China 31(2021) 1784-1795 Selective depression of copper-activated sphalerite by polyaspartic acid during chalcopyrite flotation Qian WEI, Fen JIAO, Liu-yang DONG, Xue-duan......
:Effect of frothers in preventing bubble coalescence during flotation of minerals has long been investigated. To evaluate the performance of a frother, an apparatus to measure the bubble size is a basic.... It was also noted that the frother concentration which has been so far practiced in plant measurements (CCC75-CCC95) is high enough to prevent coalescence with the bubble viewer.Key words:flotation......
realize the flotation of the ores at a low temperature and play an important role in saving energy to some extent. Compared with oleic oil, the benzohydroxamic acid had a great advantage in removing iron... and reduce the consumption of oleic acid collector, but also enhance the collecting performance of oleic acid at low temperature, which can realize the flotation of the ores at a low temperature......
