Bauxite ore beneficiation methods. Beneficiation of ores may be defined as the method of upgrading and enriching the useful mineral content of the ores, by removing undesirable and deleterious components. The processes adopted depend on the physical and chemical characteristics of the ore minerals, to take advantage of properties like specific ...
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 ().Examples of beneficiation processes include froth flotation and gravity separation.. Other economic uses of the term are in use.
Jan 29, 2014· Pisolitic bauxite ore is an ideal ore for various reasons. It is located close to the surface so very little cover is needed to be removed to expose it. The bauxite is loose and easily mined with front-end loaders. Beneficiation of the ore before it is shipped out …
