The Cuprex™ metal extraction process produces cathode-grade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrates. The process incorporates several novel steps to overcome the major problems associated with earlier chloride-based processes, including mild leaching conditions using ferric chloride as leachant and solvent extraction of copper usinga ...

Extraction of Copper from Copper pyrite | Grade 12 Science ...

The principal ore of copper is copper pyrite and copper is extracted from this ore. The different steps in extraction of copper are: Crushing and Concentration: The ore obtained from mines are broken down into small piece by jaw crusher and then pulverized. The ore being sulphide ore is concentrated by froth floatation process.

Copper: smelting, producing and classification-Metalpedia

Copper: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

Chapter 6 Copper Production Technology

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper …

Copper recovery using leach/solvent extraction ...

understand the leaching process or to maximize copper recovery. While some fundamental leaching studies had taken place8,9, on the whole leaching was a poorly practiced art and little had been done to make it a well-practiced science. Solvent extraction for copper was not yet proven commer-cially so most copper companies were taking a wait and see

copper processing - Roasting, smelting, and converting ...

Copper in solution from a hydrometallurgical process is recovered in a similar electrolytic cell using a lead anode. Here, the electric current removes the copper from solution rather than from the anode, for deposition on a cathode starter sheet (when the metal is plated from solution in this manner, the process is known as electrowinning ).

Innovations: Introduction to Copper: Mining & Extraction

The process yields concentrates containing roughly 30% copper, which are sequentially fed to a smelter, a furnace in which most of the some iron and sulfur are removed, then to a converter or converting furnace, where most of the remaining iron and other impurities are removed. (Depending on the type of smelting and converting furnace used, as ...
