Gravity Concentration
Oss and Erickson (120) have described the use of a γtransmission gauge to maintain the density of circulating slurry within ±0·05 g/cm 3 on a heavy media plant for iron ore purifiion. In the production of highquality iron pellets, γgauges are used to control the solids content of magnetite slurry to 65 + 0·5%.

Gravity Concentration of Iron Ore
Dec 01, 2007 · Gravity concentration process is the oldest beneficiation method known to mankind. This is a physical process and exploits the differences in densities of minerals to bring about a separation. Although with the advent of froth flotation, the relative importance of gravity concentration has declined in twentieth century but still on an average higher tonnage of material is treated by gravity ...
