Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage

The beneficiation of lithium minerals from hard rock ores

2019-1-15 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
