Environmental impact of phosphate mining and beneficiation

There are two types phosphate mining methods based on the depth and deposit geometry, the surface (strip) mining method (for deposit up to 100m) and the underground mining method (for deposit greater than 100m). However surface mining such as strip mining can affect a wide area than underground mining does, therefore, can be an important factor of environmental degradation.18 Beneficiation is

Gemstones and Sustainable Development Knowledge

The mining techniques adopted to extract gemstones invariably reflect the nature of the deposit: primary deposits (in hard rocks, worked underground or in open pits) and secondary deposits (found in sedimentary, soft-rock, placers). The mineralogy of a gem dictates the type of geological environment in which it can be found. The necessary stone ingredients, temperatures, and pressures
