The global market has announced copper as a modern energy metal and finds its extensive utilization in the construction industry, electrical wiring, power transmission lines, alloying, anti-corrosive coating, heat exchangers, refrigeration tubing, etc. Copper ore is primarily beneficiated from sulphide mineral deposits.
In mixed ores, nickel, zinc, or lead can accompany the copper; when such ore is mined, these other metals also are refined and sold as by-products. The table shows the ore minerals of copper and their compositions.

In developing and utilizing copper ore resources, the classification operation of copper ore concentrator is also an important production link of copper ore separation. With the increasing difficulty of copper mining and sorting, the requirements for screening and classification efficiency are getting higher and higher. Therefore, …
The mined copper ore contains from 0.8 to 1.8 % Cu and Ag, Pb, Zn, Ni, Co, V and Mo as accompanying metals. The paper presents difficulties in upgrading the LGOM ore and selected possible ...
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.
Sensor-based ore sorting is a technology used to classify high-grade mineralized rocks from low-grade waste rocks to reduce operation costs. Many ore-sorting algorithms using color images have been proposed in the past, but only some validate their results using mineral grades or optimize the algorithms to classify rocks in real-time.
The flotation separation of Cu-Fe sulfide minerals at low alkalinity can be achieved using selective depressants. In the flotation system of Cu-Fe sulfide minerals, depressants usually preferentially interact with the pyrite surface to render the mineral surface hydrophilic and hinder the adsorption of the collector. This review summarizes …
The selective separation of individual mineral from complex ore is not possible without the use of depressant to inhibit flotation of gangue minerals or valuable minerals in sequential flotation. ... The role of Na2S2O5 and activated carbon on the selective flotation of chalcopyrite from a copper ore using a dithiophosphine-type …
The copper ore bearing enargite mineral contained 5.87 mass% As and 16.50 mass% Cu while the chalcopyrite bearing ore contained 0.32 mass% As and 21.63 mass% Cu. The two ore samples were mixed at ...
Mineral processing is the process in which chemical or physical methods are used to separate the useful minerals in the ore from the useless minerals (usually called gangue) or hazardous minerals, or to separate multiple useful minerals. ... and also has the records about separation of iron ore and copper ore. According to this book, the …
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in …
Copper oxide ore is characterized by low ore grade, fine embedded particle size and severe slime coating, which is a difficult ore to be processed in China [1].Malachite [Cu 2 (OH) 2 CO 3] is a classic type of copper oxide and can be widely applied in copper metal extraction [2].And it is a type of hydroxy copper carbonate, which is formed by …
Flotation of Copper-Lead Ore. The separation by flotation of copper from lead or zinc minerals can hardly be said to be standardized at present, and no more than a brief account of the usual procedure will therefore be given. The methods in general use have a more or less similar basis in that they are variations of the standard process for …
