Copper Mining and Processing Processing Copper Orpper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the differentCopper Flotation Mineral Processing & MetallurgyMay 16, 2016· Metallurgical ContentA Copper Flotation FlowsheetCOPPER MININGCRUSHING COPPER ORECOPPER ORE STORAGEGRINDING COPPER ORECOPPER FLOTATION CIRCUITCOPPER THICKENING AND FILTERINGPROCESS CONTROLSCopper Flotation Process SummaryFlotation of Copper Ores Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, theCommon & Basic Formulas for Mineral Processin
In , approximately 103,300oz of gold and 9Mlb of copper were sold from the Boddington mine. The mine produced 709,oz of gold and 77Mlb of copper in . Processing at Western Australias copper and gold deposit. Ore containing copper and gold is crushed to a coarse size before the ore is sent to the treatment plant via a conveyor.

Mar 20, · The simplest case may be represented by a low grade copper ore which in its natural state could not be economically shipped or smelted. The treatment of such an ore by flotation or some other process of concentration has this purpose to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so.

After thickening, slurry is often stored in ponds or impoundments. Alternatively, it can pumped into a belt press or membrane filter press to recycle process water and create stackable, dry filter cake, or "tailings". Thermal drying is usually used for fine particles and to remove low water content in the particles.

Ore processing includes three stages of crushing primary and secondary ball mill grinding, conventional flotation using either standard or column cells, and water removal by thickening and pressure filtering to produce copper and zinc concentrates.

(c) The concentrated copper (I) sulphide ore (copper glance), Cu2S is roasted in air when a part of copper (I) sulphide is oxidised to copper (I) oxide. 2Cu 2 S(s) + 3O 2 (g) 2Cu 2 O(s) + 2SO 2 (g) When a good amount of copper (I) sulphide has been converted to copper (I) oxide, then the supply of air for roasting is stopped.

The properties of tailings are dependent on the ore body being mined, the grinding and processing circuits, the reagent properties and the thickening process prior to disposal. For mines with similar operating parameters the tailings properties can still vary as processing plants never operate identically to one another.

Codelco (Corporación Nacional del Cobre de Chile or, in English, the National Copper Corporation of Chile) is a Chilean state owned copper mining company. It was formed in 1976 from foreignowned copper companies that were nationalised in 1971.. The headquarters are in Santiago and the sevenman board of directors is appointed by the President of the Republic.
