Separation and Concentration Mineral Processing ...

Chemical leaching. Magnetic and electrostatic. Gravity. Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining ...

Mineral Extraction - an overview ScienceDirect Topics

The ore is then crushed into finely ground tailings for chemical processing and separation to extract the target minerals. After the minerals are processed, the waste rock and mine tailings are stored in large, above-ground piles and containment areas. These waste piles, along with the bedrock walls exposed from mining, pose a huge environmental problem due to metals pollution associated ...

Separating minerals from waste Mining of mineral ...

The valuable minerals are then separated from the rock using a variety of physical and chemical separation methods. People have extracted minerals, for example iron and copper, from ores for thousands of years. Examples of how minerals were mined long ago can be found at archaeological sites in South-Africa, such as Mapungubwe.
