Scheelite CaWO 4 and wolframite Fe Mn WO 4 are the only tungsten minerals mined commercially and are mainly found in five types of deposits: skarn vein/stockwork porphyry disseminated and stratabound.Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore and gravity and/or magnetic separation for wolframite ore.
In the beneficiation method of scheelite sulfide ore is generally floated first followed by floatation of scheelite. The flotation of scheelite is carried out in alkaline medium and the pH of the pulp is adjusted to 9-10.5 with sodium carbonate and sodium hydroxide.
Gravity concentration and flotation are the beneficiation techniques most commonly applied to scheelite ore and gravity and/or magnetic separation for wolframite ore.
Scheelite particles are brittle and easily overground in the grind process .As a result there are always a large number of micro-granular slimes in the scheelite pulp which weakens the flotation environment and leads to the loss of the valuable minerals creasing the size of flotation bubbles is regarded as an efficient way to recover the fine
