Selective flotation separation of bastnaesite from calcite using
The cation reverse flotation is a widely used method in improving the grade of iron ore concentrate, but hematite depressant is the key. In this work, the flotation behavior of hematite and quartz using the complex of Fe(III) and xanthan gum (Fe(III)-XG) as depressant was investigated via micro-flotation tests.

Flotation studies of fluorite and barite with sodium petroleum
As reported, SPS has been extensively applied in the flotation of silicate and iron ores [9], [10], [11], but seldom have researchers examined the performance of SPS in the flotation of fluorite or barite. Apart from collectors, depressants are vital to achieve desirable separation results in fluorite ore beneficiation.
