Use Of Dense Medium Separation In Iron Ore

2019-8-22  Mining Iron Ore Mines In Brazil. Dense Medium Separation is also capable of handling a wide range of feed densities, starting as low as 1.7 SG up to 4.5 SG for specific ore bodies. Dense Medium Separation utilises a fine suspension of solids within an aqueous carrier fluid to create a medium of intermediate density, relative to the process.

2010-9-1  Typically, run-of-mine iron ore is crushed to be −100 mm for liberation of Fe-rich component such as hematite. The ore particles of +6 − 100 mm in size are treated by the wet dense medium separation , for which the density of the dense liquid is adjusted at 2750–3150 kg/m 3. Although development of dry separations for iron ore is strongly needed, the dry dense medium separation has not been tested for iron ore.

2018-2-20  Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
