Sulphide Gold Ore Treatment by Leaching and Flotation

There are many arrangements and combinations using flotation in conjunction with treatment of gold ores. The two gold process flowsheets shown, with some variations, are probably the most commonly used.. In Gold Flowsheet No. 1 the ore is ground in water to such a size as to free the minerals sufficiently to produce a tailing by flotation low enough in value that it may be discarded.

Gold processing 101 Mining Magazine

Gold processing 101 In the case of Goldstrike, this was a double-refractory ore combining sulphide-occluded gold with preg-robbing carbonaceous material that rendered the ore unsuitable for conventional cyanide leaching and carbon adsorption. In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is

Gold mineral processing

To complicate matters further, these ore bodies are often refractory, where the gold is locked within sulphide minerals; or double refractory, in which gold is locked within sulphide minerals and preg-robbing due to the presence of organic carbon. These must be pretreated ahead of leaching.

How to Extract Precious Metals From Sulfides Sciencing

Extract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers. Crushing begins the separation process by preparing the ore to be floated in water. First, the ore is crushed using a gyratory crusher to reduce the ore to 6-inch diameter pieces. Then wet grinding, mill grinding and/or semi-autogeneious grinders are employed to reduce the ore

Rcovery of gold in pyritic ores Mine Engineer.Com

Geologists and mineralogists have many theories why and how the gold occurs with the pyrite, and I will not enter into any of these areas, since I am concerned with liberating the gold from the ores. I will say that from my understanding, many seem to agree that in sulfide gold ores, the occurrence of gold appears to occur as a replacement of other minerals, possibly iron. One Uliming paper

Roasting (metallurgy) Wikipedia

Roasting is a process of heating of sulphide ore to a high temperature in presence of air. It is a step of the processing of certain ores.More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth flotation.
