Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process. The phosphate ore, or "matrix" as it is called locally, contains three different mineral groups which have to be separated from each other.
Conventional mining methods are more economical but are less environment friendly due to more quantity of waste produced. While, mechanized marble mining has a better …
The modern boron applications have adsorbed the mineral processors' attention to improve typical boron mineral's (BM) beneficiation methods. In this regard, dry treatment and pretreatment processes—such as magnetic separation and calcination as environmentally friendly methods, due to their minimal or zero adverse effect on the …
