Flotation testing has been done at laboratory scale on hematite mineral and ore samples using stage additions of various hydroxamates. Chemisorption of hydroxamate species onto the hematite surface was inferred from the results, possibly involving both the undissociated hydroxamic acid and hydroxamate ion as maximum recovery occurred close to the pKa of the hydroxamic acid....

Flotation systems for removing silica from magnetite ores have to be designed differently from flotation systems for the treatment of hematite ore. In magnetite flotation, the collector must be able to float mixed magnetite-silica grains in hematite flotation, the typical need is to float fully liberated quartz from hematite.

2017-11-193.1. Effect of Citric Acid Dosage on Flotation of Articial Mixed Ore In order to study the effect of citric acid on chlorite in hematite reverse otation system, the dosage of citric acid with different hematite granularity size were tested. The pH of the pulp was adjusted to 11.5 14,15, and the results were shown in Figure1.

The adhesion behavior between particles in the pulp will seriously affect the index of concentrate. In this paper, the effect of citric acid on chlorite in hematite reverse flotation system was studied. The flotation test and settlement test of artificial mixed ore showed that a lower dosage of citric acid could significantly improve the removal rate of chlorite.
