The content of oxidized ore varies with oxidation depth. Ores can be divided into oxidized ores, sulfide ores and mixed ores. The oxidation rate of ores means the mass fraction of ores, Metals contain mineral oxygen in the presence of oxide minerals. Generally speaking, minerals with higher oxidation rate will have a looser structure and more mud content. Therefore, beneficiation will be more difficult.
The separation of copper sulfide minerals and iron sulfide minerals can also be called the separation of copper and sulfur. The copper sulfur separation scheme is usually the preferred flotation, mixed flotation or preferential mixed flotation process, in which copper first passes the preferred flotation. The use method of the reagent is as follows: The pyrite inhibitor is ordinary lime, and the collectors in PH=12 environments and copper sulfide are usually xanthate or xanthate and oil slick. Mixed flotation is usually carried out in neutral medium. Lime is added to increase the PH value of the slurry and inhibit the concentration of copper and sulfide separated from pyrite in the mixed flotation process. Floatability will vary with impurity content.
Copper sulfate is a common activation in the flotation of sphalerite. Zinc sulfate, ferrous sulfate, sulfite, sodium sulfide, thiosulfate or sulfur dioxide gas can inhibit the flotation of Verbena. There are two flotation methods for copper and nickel, which are preferred flotation and mixed flotation. The preferred flotation method is suitable for this ore because the copper content is higher than that of nickel and the mineral symbiosis is less complex. Copper and nickel concentrates can be easily obtained in the preferred flotation. However, nickel ore is severely inhibited, which leads to low nickel recovery. Therefore, this method is not often used.
