Coarse-particle flotation applied to copper sulfide ores

However, it is known that, for sulfide minerals, the best recoveries are usually obtained when conventional flotation cells process particle sizes in the ranges of 30 µm to 150 µm. In industrial operations, particles that are outside this range are generally reported in tailings, due to the

An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. The process mineralogy analysis showed that the sulfur content reached 46.21%, and 81.97% of the sulfur existed as elemental sulfur which was the major mineral in the residue and primarily existed as pellet aggregate and biconical ...

Lime use and functionality in sulphide mineral flotation: A ...

The flotation response of sulphide minerals and their interactions with collectors (xanthates, dithiophosphates, thionocarbamates, and their derivates) is strongly pH dependent. Selective flotation, of one mineral over another, can thereby be achieved by varying the pulp pH.

Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).

The most commonly used collector for flotation chalcopyrite is xanthate, chalcopyrite is easy emerged in a wide pH range (3 to 12). Chalcopyrite is susceptible to inhibition by cyanide and oxidants in the alkaline pulp. Excess lime and sodium sulfide and ammonium sulfide inhibit chalcopyrite in alkaline slurries.

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...
