Froth Flotation of Tungsten Ore

Froth Flotation of Tungsten Ore

Flotation of Scheelite. General practice for flotation of scheelite is in alkali circuit using either soda ash or lime for pH control. Plant practice at King Island scheelite involves conditioning of feed pulp to 10.2 pH using NaCO3 and floating a scheelite concentrate using oleic acid emulsified with akypomine.

Extraction of Tungsten from Scheelite Ore

Extraction of Tungsten from Scheelite Ore

A marketable grade of scheelite is rarely, if ever, made by flotation, but an increased recovery is realized by its use and the product can be treated by soda ash solution in an autoclave. In this process the scheelite is dissolved and, by addition of lime, calcium tungsten, or synthetic scheelite, is precipitated.

Froth flotation of scheelite A review ScienceDirect

Carboxylic acids, particularly fatty acids, are the main collectors in use in froth flotation of scheelite [33]. As a matter of fact, fatty acids dominate non sulfide flotation in general as they allow the flotation of many minerals [40]. They also have the advantage of being uncritical for the environment [41].
