اقرأ أكثرThe Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production. Using today’s compact mining equipment, copper ore is extracted from the mine. After the ore is crushed, it’s roasted, which helps to convert sulfides to oxides.
اقرأ أكثرWhen an ore has a low percentage of the desired metal, a method of physical concentration must be used before the extraction process begins. In one such method, the ore is crushed and placed in a machine where, by shaking, the heavier particles containing the metal are separated from the lighter ...

اقرأ أكثرSince there are a lot of pyrometallurgical copper smelters in Japan, this recycling process is applied for PGM scraps such as spent electric circuit boards. The scraps containing precious metals are fed as the raw materials into the copper smelting process, together with ore concentrates. The resulting crude copper contains the precious metals.
اقرأ أكثرChina has rich sources of copper, while copper ore concentrate in our country can be described as poor, thin. This situation occurs in many places. Since Xinhai has different mining solutions to process copper concentration. For excellent natural floatability of copper sulfide, its concentrate is relatively simple.

اقرأ أكثرThe process of liberation of copper ores depends upon whether they are oxide or sulfide ores. Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
