Feb 01, 2015& 0183;& 32;For placer deposit ores the flotation mechanisms by using sodium oleate and hydroxamate as the collectors also have been studied. Surface properties and flotation behaviour of xenotime using sodium oleate as a collector were investigated by Cheng et al. 1994 . It was found that the adsorption process on xenotime surface is strongly pH dependent.Cited by: 24

Ore Beneficiation - an overview ScienceDirect Topics

Ubiquitous microorganisms inhabiting iron ore deposits are useful in iron ore beneficiation e.g., removal of alkalis, silica, clays, phosphorous, and alumina . Because the presence of phosphorous in the iron ore promotes bacterial growth as an energy source , iron oxide particles having higher phosphorous contents were seen to be colonized by
