Once the copper-rich solutions are collected they can be processed by either of two processes—the cementation process or the solvent extraction/electrowinning process (SXEW). In the cementation process (which is rarely used today), the copper in the acidic solution is deposited on the surface of scrap iron in exchange for the iron.

Aug 21, 2020· Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico. from Rob Lavinsky (iRocks) under a CC-BY-SA-3.0 license.

Cementing on copper - Gold Refining Forum

Copper extraction from raw materials is obtained by two main methods, Pyrometallurgy and Hydrometallurgy [5]. About 80% copper-from-ore is obtained by flotation, smelting and refining; nearly all sulfide type minerals such as Chalcopyrite, Covellite, Chalcocite and ...
