Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

What types of plant are found on mining operations?

Classified plant is required by the regulations to fully comply with specific Australian Standards. Furthermore, certain types of classified plant require registration with the State Mining Engineer before they can be used on a Western Australian mine site.

Innovative Solutions for Seawater Use in Mining Operations

Sep 29, 2016 The use of seawater in mining generates a series of challenges ranging from the same take of the seawater until its use in the mining plant. Its use must consider economic, environmental, and social aspects. In the Atacama Seawater project, we have taken part of these challenges, some described in this chapter.

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
