The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.
Copper Mining and Processing: Processing of Copper Ores. Copper 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.

Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers. Large amounts are also used to make alloys such as brass (copper and zinc) and bronze (copper, tin, and zinc).
3. Processing of Copper Ore. The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps.
Home » Minerals » Copper. Copper Mineral Properties and Uses Article by: Hobart M. King, Ph.D., RPG. Copper: Copper from Bisbee, Arizona. This specimen is approximately 2.5 inches (6.4 centimeters) across. ... and its properties allowed it to be easily worked without a required processing step. Today most copper is produced from sulfide ores.
The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method.
Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of real-time technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a …
Most of the world’s copper comes from the minerals chalcopyrite and chalcocite. Chrysocolla and malachite also are mined for copper. Other copper-bearing minerals include atacamite, azurite, bornite, brochantite, cuprite (copper oxide), dioptase, rosasite and tetrahedrite.
Concentrate Thickening and Filtering. The lead-copper concentrate also contains the major part of the gold and silver values present in the ore. The high gold recovery possible by a flowsheet of this type is augmented by the Mineral Jig which recovers the coarse free gold. The amalgamation residue, which is high grade lead,...

Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching of oxidized ores.
Mineral processing. The most important sulfide sources, the copper-cobalt ores of Congo (Kinshasa) and Zambia, are processed in the conventional manner to produce a copper-cobalt concentrate. This is then treated by flotation to separate a cobalt-rich concentrate for treatment in the cobalt circuit.
The mines in the Keweenaw Peninsula in Michigan and the surrounding area (Houghton, Ontonagon, and Keweenaw Counties) produce the greatest abundance of the mineral Copper, and are the best-known locality of this mineral.
The first step in the chalcopyrite processing is to liberate the copper minerals and remove waste constituents such as alumina, limestone, pyrite and silica so that the copper and non-ferrous mineral values are concentrated into a product containing between 20 to 30 percent copper.
The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment.

Since the purpose of mineral processing is to increase theeconomic value of the ore, the importance of the recovery-grade relationship is in determining the ...
Copper Applications in Metallurgy of Copper & Copper Alloys. Such ores are called porphyries. Where mineralized rocks become outcropped or shattered, the sulfide minerals undergo chemical changes due to air, groundwater and heat, giving rise to the other main variety of copper minerals - the oxidized ores.
As the acid trickles through the ore, it combines with the copper, producing a weak copper sulfate solution. The so-called 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electro-winning (or SX-EW).
Flotation Process Of Gold ~ Technology Industry Of Gold Mining. The process of mineral flotation concentrates on mining gold is a separation process used to produce a gold concentrate copper.
Copper is a common element in many minerals and sometimes occurs in pure, native form. Most of the world’s copper comes from the minerals chalcopyrite and chalcocite. Chrysocolla and malachite also are mined for copper.
From Greek "kyprios", of Cyprus, the location of ancient copper mines; Latin "cuprum". Copper Group. Copper was one of the first metals to be worked into implements and the first metal to be smelted from ores. Its excellent ductility and high conductivity assure its use in modern society.

The powdered ore is mixed with a special paraffin oil which makes the copper mineral particles water repellent. It is then fed into a bath of water containing a foaming agent which produces a kind of bubble bath. When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of foam.
