The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.

A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.

This process is only one truly continuous process established in a commercial scale all over the world, which has a superior technology for copper smelting and converting. It is recognized as the most cost effective and environmental friendly process, and yielding anode copper directly from copper concentrate
Iron Ore Processing for the Blast Furnace. The process of mining low -grade iron ore, or ... blast furnace process. The iron ore concentrate is now mixed and ready for the pelletizing process.
Copper Smelting Industry Description and Practices ... and transport of ores and concentrates. Some vapors, such as arsine, are produced in ... The smelting process typically produces less than 3 tons of solid waste per ton of copper produced. Pollution Prevention and Control.
Abstract. Chalcopyrite (CuFeS 2) is one of the most abundant copper-bearing minerals, which accounts for approximately 70 percent of the world's known copper reserves.For more than 30 years, a significant number of processes have been developed to leach copper from chalcopyrite concentrates.
At the Asarco copper smelter in Hayden, Arizona, the oxygen flash furnace is initially heated up with natural gas. It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux.
Concentrate Treatment Process. 23 SEPTEMBER 2016. PAGE 2 / Worldwide / Copper concentrate market is 60Mtpa / An average concentrate contains only 25 -28% copper prior to smelting / Concentrates increasingly contain impurities such as arsenic, lead, zinc,
A process for upgrading a copper concentrate suitable for smelting, the concentrate including gangue material containing any one or more of iron, uranium, aluminium, silicon or compounds thereof, the concentrate also including at least one of chalcopyrite and bornite, the process including the stages of: a) leaching at least a portion of the ...
In any successful hydrometallurgical process treating copper-arsenic concentrates, key results would include high copper extraction during leaching and arsenic deportment to a stable residue. As most of these concentrates also contain significant levels of gold and silver, recovery of these
The technical viability of the BRISA process for copper concentrates consisting of mixtures of either chalcopyrite and secondary copper sulphides (chalcocite and covellite) or chalcopyrite and sphalerite was studied.
In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes
The copper can be sold to wire-rod mills or further processed into rods. Anode slime refers to impurities that sink to the bottom of the electrolytic cell. The second method for refining copper is called the hydrometallurgical process. This process begins with oxidized copper ores or oxidized copper wastes.
About us "Copper Project" LTD Metallurgical Company specializes in the production of high quality products from low-grade metal-containing concentrates, which are not possible or not cost-effective to process using common techniques.
