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 ...

iron ore resources have become a national priority. As per the recent national steel policy, our country will be producing about 110 million tons of steel per annum by 2020 requiring around 42 million tons of iron ore. The iron ore exports are projected to a level of 114 million tones and it amounts to total production of 300 million tons by 2020.
