Mineral dressing (= Ore beneficiation)(= Ore beneficiation). The first process most ores undergo after they leave the mine is mineral dressing (processing), also called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate (.notes for beneficiation of an ore,notes for beneficiation of an ore,TECHNICAL NOTE TALC SEPARATION FROM . - Science DirectBeneficiation of talc from most ores involves grinding, flotation and magnetic separation of the iron oxide minerals. Flotation is the preferred concentration technique because talc is naturally floatable, requiring only a frother to affect flotation [3-71. In the current study, a representative sample of Egyptian talc-carbonate ore.

Beneficiation - Wikipedia

In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity.
