Case Study Flowsheets: Copper–Gold Concentrate Treatment .

The conventional treatment of copper concentrates by this method works well and recovers copper and precious metals as high-value products. The conventional treatment of copper–gold concentrates does have some compelling reasons to seek an alternative hydrometallurgical process for recovery of concentrate values.

The role of metal-cyanide species in leaching gold from a copper .

In this paper the role of the cyanide complexes of copper, silver, nickel, iron and zinc in gold leaching was investigated by examining the leaching of a copper concentrate. It was found that copper-cyanide and other metal cyanide species, including Ag, Fe, Ni and Zn, all play an important role in gold cyanidation under.

Treatment of a refractory gold—copper sulfide concentrate by .

However the leaching of gold tellurides was slow and high concentrations in a concentrate would be expected to reduce recovery. There was no evidence of partial alteration of pyrite in the leach which would suggest that gold inclusions present in pyrite grains will not be recovered until some pretreatment process is carried.

Gold extraction - Wikipedia

Sometimes gold is present as a minor constituent in a base metal (e.g. copper) concentrate, and is recovered as a by-product during production of the base metal. For example, it can be recovered in the anode slime during the electrorefining process. The results of laboratory and bench experimental studies can be used.

Improved Copper and Gold Recovery at KGHM . - Stat-Ease

In an effort to recover additional copper and gold at KGHM International's Robinson . differing ore types. Results indicated that up to 30% of the contained copper was recoverable along with significant quantities of gold. Based on these results, the existing ... contributor to the Robinson Mine's concentrate production.

Gold dissolution and copper suppression during leaching of copper .

This increases the cost to the gold mining companies to cover both the extra cyanide consumption in the leaching stage and the additional cost for cyanide recovery/destruction. Therefore, in this study, a selective cyanide leaching process of gold over copper from copper-gold concentrate (also see Oraby and Eksteen,.

Recovery of gold from copper-bearing ores (PDF Download Available)

Full-text (PDF) | Many gold ores have copper mineralisation which presents problems in a carbon-in-pulp operation. Various types of copper-gold ores and ways of tackling the problem are discussed. In some cases copper and gold can be upgraded to a concentrate by flotation; otherwise, copper or gol.

Metal Production from Concentrates - Aurubis

Aurubis imports most of the copper concentrates directly from copper mines in different countries. Copper ore is primarily mined in Central and South America, the US and Canada, as well as Africa, Asia, Australia and to a lesser degree in Europe. Copper ores contain about 0.5-4 % copper and are already processed into a.

Mine Engineer.Com provides mining, gold, copper, coal, mineral .

The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported.

View CESL Copper Process PDF - CESL Limited

CESL Copper Technology. CESL technology has been adapted to treat copper or bulk concentrates such as copper- nickel and copper-gold to produce a copper cathode product. The CESL Process is a medium temperature pressure oxidation of sulphide based concentrates in the presence of chloride catalytic ions. A light.

extraction of gold, silver and copper from the copper . - Cetem

Copper sulphides Concentrates, from the flotation process of copper primary ore; contain, commonly, small amounts of precious metals, such as gold and silver. During the smelting process of those concentrate all gold and silver are practically in the blister copper, which is cast into anodes. Those copper anodes are.

Method for the recovery of gold from sulphide concentrate - Google

Copper concentrates contain variable amounts of gold. In smelting plant processes gold is generally recovered with a high yield via anodic sludge treatment processes. In hydrometallurgical copper processes the recovery of gold from concentrates causes a specific problem. Gold recovery in process alternatives using.

Deflector Gold Copper Project | Doray Minerals

Deflector is a shallow, narrow vein, high-grade gold and copper underground mine. The ore is located in three separate lodes being the West, Central and Contact lodes. A fit-for-purpose processing facility was constructed to enable recovery of gold from a gravity circuit prior to the production of a copper/gold concentrate.
