The mineralogical characterization of Itakpe iron ore shows that it contains mainly hematite, magnetite and quartz whose specific gravities give sound basis for adopting the gravity concentration technique. In this study, the effectiveness of gravity techniques for concentrating iron ore from bulk Itakpe (Nigeria) iron ore was studied

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
