LECTURE NOTES
Scope of Ore Beneficiation: Previously selective mining practices were followed. But after the development of inexpensive ore beneficiation methods, bulk mining practices have proved to be more economical compared to careful selective mining. In a general way the scope of mineral dressing or ore beneficiation is twofold: 1.

In many lithium ore beneficiation plants, it is a common practice to de-slime the ore prior to flotation. De-sliming is typically carried out to remove the −20 µm size fraction to improve selectivity of separation because slimes are detrimental to the flotation circuit (Bale and May, 1989). As is the case in many operations, de-sliming is ...
