Mineral Tailing Extraction Equipment Price

Mine tailings are materials left over after extraction of valuable minerals from ore. They are distinct from “waste rock” that miners move and discard along with soil and organic matter as they dig down to access the underlying ore.

The size and composition of the tailings varies depending on the mining method. In hardrock metal mining the ore is usually crushed, then processed, resulting in very fine particles that may also contain chemicals used for mineral extraction.

Mineral Tailing Extraction Operation

Disposal of mine tailings is usually the single biggest environmental concern facing a hardrock metal mine. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water.

The extraction process is designed to remove ore of a predetermined grade or higher, leaving behind as much of the lower grade ore and barren rock as possible. Because this ideal separation is not always possible in practice, some lower grade rock is mined while some higher grade ore is left behind. It is important to note that the term “ore” is an economic one. In general, ore is earthen material that contains minerals of sufficient value to be extracted economically.

Mineral Tailing Extraction Equipment

Most ores contain the valuable metals disseminated in a matrix of less valuable rock called gangue. The purpose of ore beneficiation is the separation of valuable minerals from the gangue to yield a product that has a much higher content of the valued material. Beneficiation milling operations are functionally categorized as either comminution, in which the mined ore is crushed and ground to physically liberate the target mineral, or concentration.
