Environmental impact of phosphate mining and

2018-6-28  There are two types phosphate mining methods basedon 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 the process of removing the unnecessary minerals, which is used to increase the grade of mining product (concentrate). Phosphate ores can be beneficiated
