In a concentrator, gravity separation methods are methods of separation based on the difference in specific gravity of minerals. The main gravity separation methods used in concentrators today include shakers, cyclones, centrifugal separators, heavy media separation, and spiral concentrators.
In recent years, with the advancement of science and technology and the continuous development of mining technology, more and more composite iron ores have been discovered, which contain a variety of non-ferrous useful minerals that can be comprehensively utilized. These associated minerals can not only increase the economic value of the ore, but also effectively utilize resources and reduce environmental burdens.
The main task of mineral processing plant design is to effectively separate useful minerals, gangue minerals and impurities in the raw ore through physical and chemical methods, so that the products meet the needs of smelters or other users. Common physical mineral processing methods include gravity separation, flotation and magnetic separation; chemical mineral processing methods include roasting, leaching, adsorption, replacement and extraction. The design of mineral processing methods is mainly based on the characteristics of the raw ore and the production needs of the mineral processing plant.
High-sulfide gold ores contain a high proportion of sulfide minerals such as pyrite and arsenopyrite, in which the gold grade is relatively low, and the natural gold particles are fine, usually tightly wrapped by sulfide minerals such as pyrite. The characteristics of this type of ore are that gold and sulfide are closely related, resulting in a low gold recovery rate in the direct leaching process, and high consumption and production costs of gold leaching agents. Therefore, for high-sulfide gold ores, the direct cyanide leaching process is not recommended.
