Oss and Erickson (120) have described the use of a γ-transmission gauge to maintain the density of circulating slurry within ±0·05 g/cm 3 on a heavy media plant for iron ore purification. In the production of high-quality iron pellets, γ-gauges are used to control the solids content of magnetite slurry to 65 + 0·5%.
