Tungsten Extraction Process
The Beneficiation flowsheet shown with this study is particularly adapted to the concentration of tungsten ore in small tonnages. Tungsten minerals are generally in the friable class and therefore concentrating processes are hindered by the excess amount of fines produced in the crushing and grinding steps. Special consideration must be given to the stage reduction …

Basic Principles of Metallurgy and Metalworking
*Beneficiation is any process that improves or benefits the economic value of the ore by removing the gangue (or commercially worthless material) that surrounds the mineral, thus resulting in a higher grade product (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity

Themed issue on 'Modelling of mineral beneficiation and metallurgical
Modelling of a metallurgical or mineral beneficiation process is an attempt to reproduce the description of the process as close to the reality as possible. If attempts are made to develop models based on theories only, even if they are sound, such descriptions can only be termed as Idealized Models.
