starch for iron ore beneficiation

Investigations on different starches as depressants for

Aug 01, 2013 Out of the four different starches studied, soluble starch was found to be the most effective one, with an iron grade of 63.8% at a starch concentration of 400 g/t. In case of corn starch, rice starch and potato starch, the highest grades of 60.31%, 60% and 58.5% iron were achieved at a starch concentration of 250 g/t

The Use Of Starches And Starch Derivatives As Depressants

British gums and dextrins were beneficial for oxidized iron ores, but none of the starches or starch derivatives appeared to have any effect on magnetite-taconite concentrates. The flocculation and filtration of iron ore slimes were most strongly affected by the level of starch, to a lesser degree by the pH, and were virtually independent of the level of calcium chloride
