US3639925A - Recovery of gold from carbonaceous ores - Google ...

Carbonaceous gold ores are rendered amenable to a conventional cyanide recovery process by pretreatment with sodium hypochlorite or calcium hypochlorite compounds at temperatures under 70* C. Hypochlorite solutions can be generated in situ by electrolysis of chloride solutions.

Agglomeration Drums for Processing Gold Ore

The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. While this method has been used for decades with success, it has been greatly improved by the addition of an agglomeration drum to the process before the heap.

Analytical electrolysis equipment The Nile Co., Ltd.

Analytical electrolysis equipment is a set of gold ore beneficiation equipment that obtains gold mud from gold-laden carbon through desorption and electrolysis under normal temperature and pressure conditions. This equipment can well desorb the gold-laden carbon produced by the gold mine coal pulp plant and heap leach plant. Advantages

GB2310424A - Recovering gold from oxide ores - Google Patents

A method for recovering gold from oxide ores containing 0.5 to 7.5 weight % of carbonaceous materials comprises leaching the concentrated ore with an alkaline thiosulfate eg ammonium thiosulfate solution to which an oxidizing agent and a stabiliser are added, gold being separated from the resulting saturated slurry by a zinc cementation precipitation method.

Free gold recovery by coal-oil agglomeration

from its ores. The Coal Gold Agglomeration CGA process was developed some years ago and has the advantage in that gold is recovered by a procedure which has little or no negative impact on the environment. A gold ore containing liberated gold particles is contacted with coal-oil agglomerates, whereby the gold is recovered into the coal/oil phase.

An Introduction to the Electrolysis Process

Electrowinning is an electrolysis process that is used for recovering metals in aqueous solution after the ore undergoes one or more hydrometallurgical processes. Fused salt electrolysis is a type of electrometallurgical process in which a metal is dissolved into a molten salt which acts as the electrolyte, and the metal collects on the hode ...

Alternatives to cyanide in the gold mining industry: what ...

6. Coal–oil agglomeration. The coal–oil–gold agglomeration CGA method has been identified as an alternative to cyanide for large-scale operations. More recently, it has also been promoted as an alternative to mercury amalgamation in the small-scale artisanal gold mining industry.

Extracting Metals by Electrolysis

What is electrolysis? Electrolysis is a process that uses electricity to separate the elements in a compound. Electrolysis is expensive and so it is only used to extract reactive metals that cannot be extracted in other ways. Aluminium is a reactive metal that is found in the ore bauxite as aluminium oxide Al 2 O 3 .
