The objective in beneficiation of iron ore/ fines/ slimes is to treat mechanically, chemically and other methods. The beneficiation process can be classified into two categories, namely Mechanical Separation & Float Flotation by
The Coons-Pacific was designed with five distinct sections for treating low-grade ore: a scalping (removal of dirt, foreign material and general crud by means of vibration) and crushing section; a washing section; a Heavy Media Separation (HMS) section; a jigging section; and a spiral section. The design of the Coons-Pacific Concentrator drew from the success of …
Crushing is done in the conventional manner in 2 or 3 stage systems to approximately all minus ¾ inch which is considered good feed for subsequent wet rod and ball mill grinding.
