An approach to environmental sustainability and improved process economy, in sulphide minerals production is recycling of process water in flotation of complex sulphide ores, although the chemistry.
Jan 01, 2017 Base metals such as copper, lead, and zinc are mainly extracted from sulfide ores. Mostly these base metals tend to exist together in an ore. Flotation process is widely used to separate these minerals in sulfide ores . A wide range of chemical reagents are used in the flotation process to separate the different minerals.
Copper processing is a complicated process that begins with mining of the ore (less than 1 copper) and ends with sheets of 99 99 pure copper called cathodes which will ultimately be made into products for everyday use The most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy.

How to Process Copper Ore Beneficiation Methods and Oct 27, 2020 Basically, only flotation can be considered in its separation. Almost all copper sulphide ores contain ironbearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of copper sulfide from iron sulfide.
Addition of reagents is of special significance to the flotation of copper oxide ores, especially sodium sulfide, which is not only an activator of copper oxide ores, but also an inhibitor of copper sulfide ores. Therefore, it is not appropriate to add enough reagents at one time, usually in batches and stages.
The recovery rate of selected sulfide ore is above 90 , and the concentrate grade can be close to the theoretical grade of pure mineral. The use of flotation to treat polymetallic symbiotic minerals, such as copper, lead, zinc and other polymetallic ores can be separated from copper, lead, zinc and pyrite, and can obtain high selection indicators.
