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 ...

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).

Copper Mining and Extraction Sulfide Ores

The smelter for sulfide ores produces sulfur dioxide gas. This is scrubbed from the flue gases to make sulfuric acid for leaching copper from oxide ores. Scrubbing sulfur dioxide also protects the environment. FeO (s) + SiO2(s)→ FeO.SiO2 (slag) This is very similar to the removal of impurities in the blast furnace. The liquid left is a ...
