Copper Extraction from Oxidized Copper Ore

     

Method for Copper Extraction from Oxidized Copper Ore:

This method for extracting copper from oxidized copper ores involves a low-temperature, constant-pressure ammonia leaching process. It optimally combines wet metallurgical techniques such as "ammonia leaching - solvent extraction - electrowinning" and mineral processing techniques like "flotation" to form a novel copper-magnesium oxide ore processing flow.

By abandoning the high-temperature, high-pressure, or heating and pressurizing methods used in traditional ammonia leaching to achieve high copper leaching rates, this method leverages the advantages of ammonia leaching in easily dissolving oxidized copper minerals while also utilizing the floatation technique's ability to easily recover chalcopyrite. This significantly reduces energy consumption and costs, enhancing its practicality and economic feasibility. The process is easy to industrialize and scale up for production.
