The Mt. Gordon Copper Process was developed to treat chalcocite ores from the historic Gunpowder deposit in Northern Queensland, Australia. The process uses low temperature pressure oxidation to directly leach copper from the ore followed by SX/EW of copper from the resulting leach solution.

Writing in the SME’s 2002 handbook on mineral processing plant design, Randolph Scheffel provided an insight into more recent applications. While heap leaching for copper was under discussion in the 1920s, he said, leaching of residual material in old stopes began in 1923 at Bisbee, Arizona, USA.

Terramin Australia subsidiary Terramin Exploration (TEL) has entered a joint venture agreement with Environmental Copper Recovery (ECR) for the potential development of a new copper project in Kapunda, South Australia.

Fact Sheet Copper is a metal which is mined from the earth and used for a number of different purposes. It was formed as a result of volcanic activity which resulted in large masses of molten rock and hot water cooling and then solidifying into copper compounds.

Australia selectively mines and cyanide leaches ores containing less than 0.5 % copper, with the high copper ores being stockpiled for future processing. Flotation to produce high grade copper gold concentrates for smelting is a widely adopted technology for treating primary copper-gold ores.

Copper has been the most common base metal extracted with bioleaching and according to some estimates, bioleached copper represents up to 15% of the world’s copper production. Bio-oxidation has also been used to treat sulphide containing gold ores before leaching of the gold using chemical reagents.

A Bacox™ gold bioleaching plant, designed to treat 70 t/day of a refractory pyrite-arsenopyrite concentrate, was commissioned at the Tasmania Mine (formerly the Beaconsfield Gold Mine) in Tasmania, Australia in 1999. Near-complete oxidation of the sulfides results in a gold extraction in excess of 95 per cent.

metal ores (<1% copper, <1g/ton gold, < 0.5% nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in …

At Mount Isa, the copper ore bodies are separate from the lead-zinc-silver ore bodies, thus enabling independent production of the two ore types. Across Australia, relatively small amounts of copper are recovered as a by-product of silver-lead-zinc, nickel and gold mining. Several important copper deposits have been discovered in the past 30 years.

Similar to copper oxide heap leaching, also using dilute sulfuric acid. Rio Tinto is commercializing this technology in Namibia and Australia, the French nuclear power company Areva in Niger (two mines) and Namibia, and several other companies are studying its feasibility.

Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.

simultaneous leaching of copper and precious metals an can be applied to minerals throughout the geometallurgical spectrum associated with Cu and Cu- Au-Ag deposits.

Bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid leaching wherein only oxidized minerals are leached.

In 2001, bioleaching constituted approximately 10% of Chilean copper production and heap and dump leaching, in general, constituted approximately 30% of Chilean production. 2 The first Chilean plant to be put into operation was S.M. Pudahuel.

New techniques for tailings treatment and sulfide ore recovery will see low-cost environmentally friendly heap leaching take another giant leap forward.

Since 2001 a fast-tracked in-situ leach (ISL) mine, the Beverley uranium mine, has been operating in the northern Flinders Ranges in South Australia.

The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant, with the barred (denuded) sulfuric acid recycled back on to the heaps.
