Postcopper sulfur ore flotation process, copper ore sulfide ore beneficiation process, copper sulfur separation
1. Copper ore beneficiation mainly uses flotation method, and some use magnetic separation method, gravity separation method or Hydrometallurgy, etc.
In order to correctly select various mineral processing methods, it is necessary to study the material components and structural structure of copper ore, ascertain the natural and industrial types of copper ore, and also understand the content and general distribution of refractory minerals in the ore. wait.
2. The natural types of copper ores are generally divided into sulfide ores (containing copper oxide below %), mixed ores (containing copper oxide ~%) and oxidized ores according to the different proportions of copper oxide and copper sulfide. (containing more than % copper oxide) three types. The commonly used beneficiation methods for different types of copper ores are briefly introduced as follows:
.Ore beneficiation of single copper sulfide ore. Generally, flotation is used for beneficiation.
.Ore beneficiation of polymetallic sulfide ores. Generally, according to the different processing technology characteristics formed by its main components, mixed flotation method, preferential flotation method, mixed preferential flotation method, flotation and gravity separation combined beneficiation method, flotation and magnetic separation combined beneficiation method are used respectively. And the combined treatment of flotation and hydrosmelting, etc.
.Mixed ore beneficiation. Generally, the flotation method can be used. It can be treated alone or together with sulfide ores. It can also be treated by a combination of flotation and hydrosmelting. That is, the copper concentrate is first selected by flotation, and then the tailings after flotation are processed. Mineral hydrosmelting treatment.
.Ore beneficiation of oxidized ores. Ores containing high levels of bound copper oxide are generally processed by a combination of flotation and hydrosmelting or by a combination of segregation and flotation. Generally, hydrosmelting is used.
