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

The leaching kinetics of an oxide gold ore with iodide

Feb 01, 2012· Highlights Two gold ores were subjected to iodide/iodine leaching. The carbonaceous ore showed only 20% gold extraction. Gold extraction from the oxide ore reached 89% in 24 h. A power law rate equation was applied to model the gold extraction kinetics. Gold leaching rate was first order with respect to tri-iodide concentration.

The leaching kinetics of an oxide gold ore with iodide

The carbonaceous ore showed only 20% gold extraction, since gold–iodide complexes readily adsorb on organic matter. In contrast, gold extraction from the oxide ore in a solution containing 20 g/L iodide and 4 g/L iodine reached 77% in 6 h and 89% in 24 h. With iodate as the oxidant, no gold

Gold processing Britannica

Endogenetic gold ores include vein and lode deposits of elemental gold in quartzite or mixtures of quartzite and various iron sulfide minerals, particularly pyrite (FeS 2) and pyrrhotite (Fe 1-x S). When present in sulfide ore bodies, the gold, although still elemental in form, is so finely disseminated that concentration by methods such as

Small Scale Treatment of PM Sulfide Ores Gold Refining

Feb 15, 2020· The ore has a 5 to 10 percent sulfide content, so I expect about 10 to 20 pounds of sulfide concentrate. Dealing with 10 to 20 pounds is a lot easier than 200 pounds. There will be some loss of values in this operation but I accept this because although the method is less than optimal, it's the best I can put together.
