Froth Flotation Process - Mineral Processing Metallurgy

20/01/2021  The operation of flotation is not always confined to the separation of the valuable constituents of an ore in a single concentrate from a gangue composed of rock-forming minerals. It often happens that two classes of floatable minerals are present, of which only one is required. The process of floating one class in preference to another is termed “ selective ” or “ preferential flotation ...

Mineral processing - Wikipedia

Modern, automated sorting applies optical sensors (visible spectrum, near infrared, X-ray, ultraviolet), that can be coupled with electrical conductivity and magnetic susceptibility sensors, to control the mechanical separation of ore into two or more categories on an individual rock by rock basis. Also new sensors have been developed which exploit material properties such as electrical conductivity, magnetization,

Rutile Ore Titanium Flotation Mineral Processing

The physical and chemical properties of rutile minerals are often not different from those of associated gangue minerals. In order to obtain high grade and high recovery rutile concentrate, it is no denying to attach great importance to the froth flotation technology. The rutile titanium flotation process is a significant method for separating fine rutile ores and recovery of tailings.
