Wolframite sorting are based on gravity
separation and flotation methods. Generally use the gravity separation of
coarse recycled fine grade recovery methods often used combined processes, such
as the gravity beneficiation --- magnetic separation, magnetic separation -
flotation, gravity beneficiation - flotation method. Scheelite sorting mainly
used flotation method. For black and white Tungsten Ore, relatively fine grain
size and associated with sulphide ore, generally using flotation
machine process.
Wolframite ore sorting process is the most
important gravity beneficiation. Used a multi-stage process jig machine,
spiral chute separator, multi-level shaker, regrinding middlings, fine mud
alone treatment and so on. The gravity beneficiation of traditional wolframite
are mainly table drop tail and Jigging early harvest. With the development of
beneficiation process and technology, centrifugal concentrator and other new
devices have been developed and widely used.
