	Copper extraction - Wikipedia, the free encyclopedia
		Copper orebodies are formed when geothermal solutions bring copper dissolved from deep underground to cool near surface environments where the copper and associated metals precipitate as minerals in veins and disseminations within the rock.
		Copper concentrate may be treated by either hydrometallurgical methods or sintered before pyrometallurgical methods are used to produce copper metal.
		In the roaster, the copper concentrate is partially oxidised to produce calcine and sulfur dioxide gas.

	Hydrometallurgical copper extraction process - Patent 5316567
		This invention relates to a process for the extraction of copper from copper ore or concentrates, in particular sulphide ores, in which the concentrate is subjected to acid leaching to extract the copper therefrom.
		Copper concentrate is first ground in a ball mill to reduce the size of the particles to about 95% minus 325 mesh or smaller.
		The high copper concentration of about 15-20 grams per liter derived from the atmospheric leach 32 provides significant advantages over conventional solvent extraction/electrowinning plants because much higher loading of the organic is possible, thus reducing the size of the plant for a given tonnage of copper.

	Concentrate flows in the CIS
		Meanwhile, imports of copper concentrate to Russia from Kazakhstan grew significantly in 2000-02.
		Last year, limited exports of copper concentrate were recorded to the Almalyk Combine in Uzbekistan from Alexandrinskaya Co. in the Cheliabinsk region of the Urals.
		The company is unable to smelt all of the concentrate produced by its mines owing to its obsolete technology and the poor general condition of its smelting facilities.

	CCU-1c Copper Concentrate (Site not responding. Last check: 2007-10-24)
		CCU-1c is a copper flotation concentrate prepared from ore from the Ruttan mine, Lynn Lake, Manitoba, and donated by Hudson Bay Mining and Smelting, Flin Flon, Manitoba, Canada.
		The homogeneity of the stock with respect to its antimony, copper, gold, selenium, silver and zinc was investigated using twenty-two bottles chosen according to a stratified random sampling scheme.
		The analyses for copper were performed by CANMET on 0.5 g samples using a multi-acid digestion followed by a titration with thiosulphate.

	Process for the recovery of copper and zinc values from sulphidic ore - Patent 4279867
		An initial copper concentrate is floated in a first flotation step, and the initial copper concentrate is fed to a second flotation step to float a relatively zinc free copper concentrate.
		The intermediate concentrate may be treated with such zinc-depleted solution to dissolve zinc from the intermediate concentrate and to produce a further relatively zinc-free copper concentrate and a zinc-enhanced solution.
		Further, the intermediate concentrate treatment step enables zinc to be transferred from the intermediate concentrate to the leaching operation for subsequent recovery of elemental zinc, and also enables dissolved copper in the leach solution be be transferred to the intermediate concentrate thereby forming a further copper concentrate with minimal zinc content.

	China may abolish preferential taxation on imported copper concentrate - Metals News - Metals Place
		China is considering abolishing the preferential taxation policy for imported copper sulphide concentrate starting on Jan. 1, 2006, sources with the Ministry of Commerce said on Wednesday.
		The move aims to help cool down the overheated investment in the copper industry, the sources said, predicting a drop in both the export of refined copper and the demand for imported copper.
		Under the preferential policy, copper smelteries could import duty-free copper ores as long as their processed copper products were designated for exports.

	Phelps Dodge Corp. :: Phelps Dodge to Construct First-Ever Commercial-Scale Copper Concentrate Leaching Facility at ...
		Concentrate leaching technology, in conjunction with a conventional milling and flotation concentrator, allows copper sulfide ores to be transformed to copper metal through the efficient pressure leaching and electrowinning process instead of smelting and refining.
		The new concentrate leaching facilities will be incorporated into the existing leaching and electrowinning complex at Morenci, which is the world's largest.
		Phelps Dodge Corp. is one of the world's leading producers of copper and molybdenum, the largest producer of molybdenum-based chemicals and continuous-cast copper rod, and among the leading producers of magnet wire and carbon fl.

	Copper concentrate mating leaves smelters reeling American Metal Market - Find Articles
		NEW YORK -- More details have emerged of settlements in the copper concentrates mating season, and it now appears the major "benchmark" deals are all but concluded.
		The extreme tightness in the concentrates market has strengthened the hand of miners and, in most cases, the major mining companies have achieved lower treatment and refining charges (TCs/RCs) for 2004 compared with the second half of 2003.
		The deals struck by Alumbrera have been closely scrutinized by the industry because it is the first mating season since Xstrata AG, Zug, Switzerland, acquired its 50-percent stake in the mine through the purchase of MIM Holdings Ltd., Brisbane, Australia.
