Mineral Processing. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.

sulfuric acid. However, the free copper oxide (mala-chite) and combined copper oxide (chrysocolla) in the ore can react with the sulfuric acid, meaning that 19.70% of the undissolved Cu is copper sulfide. Therefore, leaching of the copper oxide ore yielded a low leaching efficiency and required a high temper-ature and energy …

The main raw material is copper sulfide ore, and high-grade copper oxide ore can also be smelted in the pyrometallurgical process. The mining grade of copper sulfide is 0.3–2%, and the average mining grade is approximately 0.81%. The mined ore is crushed and pulverized. Then flotation will separate the copper sulfide concentrate.

Grinding-flotation process: This process is suitable for processing copper minerals with coarse and uniform particle size, loose combination of copper minerals and gangue, and smooth and flat contact edges.Usually, the raw ore is ground to -200 mesh, accounting for 50-60%, and the copper minerals can be dissociated as …

The nickel-containing tailings go through flotation to obtain nickel concentrate or copper-nickel concentrate. Copper-nickel mixed flotation. This method can be used when the copper content is lower than that of nickel. Pump the ore pulp into the flotation machine to obtain a copper-nickel concentrate. Further process copper …

Chrysocolla type copper oxide ore. The main mineral of it is chrysocolla. It is a refractory ore and can be separated by the chemical beneficiation method. Cuprite type copper oxide ore. Cuprite-type copper oxide ore is dominated by cuprite and malachite, with high copper grade. No matter what type of gangue, it can be processed by flotation.

At the last stage of copper concentrate processing, the copper matte undergoes an electro-refining step. In this procedure, the matte dissolves in a special electrolyte solution. When an electric current passes through this solution, copper ions travel from the anode, where they start, towards the cathode.

Copper ore is generally an aggregate of copper sulfide or oxide and other minerals. The conductivity of copper is second only to silver, and it is more abundant and cheaper than silver. As one of the …

There are two big opportunities for DES in copper processing: first, the processing of copper deposits in jurisdictions with water usage sensitives and, second, the processing via leaching of transition ores and copper sulphides. "As the DES process requires minimal water usage, we only use it as an option for washing," White said.
