Optimization of Reverse Cationic Flotation of Low-Grade ...

2017-9-19  Due to gradual depletion of high-grade iron ores, there is a need to investigate the treatment of low-grade iron ores. Current procedures are time and cost intensive. Batch laboratory scale reverse cationic flotation was employed to concentrate low-grade Fe ore, found in fluorspar tails in the form of hematite. This study used two types of depressants (soluble starch and dextrin) and two types ...

Reverse anionic flotation of quartz from Muro iron ore ...

1995-11-1  The recovery of iron from low-grade (31.6% Fe) Muro iron ore was investigated using reverse anionic flotation of quartz. Tests were performed to investigate the effect of pH, the effects of using distilled vs. tap water as the flotation medium and the effects of using cassava starch vs. dextrin for the depression of iron minerals.The optimum results were obtained around pH 10 and 11, and ...

An overview of the beneficiation of iron ores via reverse ...

2014-3-10  Concurrently, flotation has significant advantages when processing low-grade, finely grained iron ores containing iron-bearing silicates. The most common flotation route used for the beneficiation of iron ores is reverse cationic flotation. This process is the major technique used to produce pellet feed fines at all Brazilian concentrators.
