The reaction of these processes can be written as: 2CuFeS2+2SiO2+4O2 → Cu2S+2FeSiO3+3SO2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2.

Aqueous metal extraction or leaching is the process of extracting metal or a valuable entity found within an object. Consider the copper minerals shown in Fig. 5.1. Each of these mineral samples contains a high concentration of copper. Most are nearly pure mineral specimens. The copper in these minerals can be extracted using a variety …

The Solvent Extraction Electrowinning (SX-EW) process offers a cost-effective, low impact way to process previously unprocessable or uneconomic deposits of copper. Combined with heap leaching and agglomeration, the effectiveness of this process is further increased. While the SX-EW process has its roots in copper and is most well-known in …

The pyrometallurgical production of copper from sulfide concentrates is a journey involving the gradual oxidation of copper concentrates in sequential steps. These steps are smelting, converting, and refining. The overall copper making process can be explained by using the copper–oxygen–sulfur predominance diagrams.

Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of …

The SX/EW Process. The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but ...

The flotation concentrate is then dewatered and filtered to produce a filter cake that is sent to a copper smelter. Copper processing - Ores, Refining, Smelting: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature.

Typical Copper Extraction Process. The process of extracting copper for its ore is quite complex and varied. It largely depends on the type of ore in question, particularly whether it is a sulfide or oxide type.

Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore.
