Mineral processing - Wikipedia

Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes, which is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considered as this dictates the amount of liberation required and the processes that can occur. The smalle

Hematite Separation Process

Magnetic separation sorts out the coarse concentrate and tailings, and reduces the working of flotation operation. Strong magnetic separation and reverse flotation technology, float little and inhibit much, more cost saving. Strong magnetic process recycles fine iron minerals, which can play a dual role of de-sliming and tailings out creating good conditions for flotation. Reverse flotation process system is simple, which can significantly reduce the flotation

Flotation as a Separation Process - Matis - - Major ...

15/07/2005  Flotation initially originated from the field of mineral processing, usually termed froth flotation. For many years, various particulate solids besides minerals have been extracted from water by using this effective gravity separation method that is based on the idea of applying rising gas bubbles as the transport medium; the attachment of bubbles to particles transfers the solids from the body of water to the surface. As opposed to settling, flotation
