Mineral Concentration Plant and Milling Minera San

The concentration of zinc, lead and silver in the mineralized rock extracted from the Jayula and Tesorera pits in the San Cristóbal mine is very low; it is therefore necessary to have the material undergo a process designed to increase the content of these elements and thus obtain products with a commercial value. In this sense, the concentration

mineral processing Concentration Britannica

mineral processing mineral processing Concentration: Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic
