Lime use and functionality in sulphide mineral

2019-11-1  Lime in flotation, as a pH modifier, can also regulate not only collector adsorption, but also the effect of other commonly-used depressants such as sodium sulphide or sodium cyanide (Yoon, 1981, Ghiani et al., 1984, Wang and Forssberg, 1996). Cyanide acts by dissolving copper from the surface of the activated sulphides, thus preventing ...
