Good day, everyone! This is Rose Yang from Xi’an DASEN Mining Machinery Equipment Co., Ltd. I am going to talk about the separation way for Tungsten tin ore beneficiation.
For tin ore and wolframite ore mixture mineral. There are some different types in nature.
The first type:
Cassiterite, also called tinstone (SnO2), a naturally occurring oxide of tin. It is colourless when pure, but brown or black when iron impurities are present. Cassiterite also occurs in granite and pegmatites.

For this rock ore, it is crushing and grinding first, then gravity&magnetic separation way is used based on the heavy and large difference density proportion.
Today most of the world’s cassiterite is mined in Malaysia, Indonesia, Bolivia, Nigeria, Myanmar , Thailand, and parts of China.

The second type:
Alluvial tin ore , it has some related minerals such as wolframite, scheelite, and columbite. We usually upgrade it to 70% to 75%, then we ship those tin concentrate to the smelter.

For alluvial ore, the best way is washing&screening first, then use gravity&magnetic separation, it is the tradition way we often use.
This method is popular because of low operation cost , easy operation and high efficiency .

The third type
There are also complex sulfide ores which normally found in underground deposits, and require more complicated mineral processing, which often involves froth flotation, in order to produce a clean tin concentrate. Even then, the average Bolivian tin concentrate may be only 50 to 60 percent as per our experience.
The gravity separation machines
we often use spiral chute and jig machines for rough concentrating, and shaking table for final concentrating.

The magnetic part
It includes double roller magnetic separator and three disc electromagnetic separator.

Especially the three-disc electromagnetic separator, it is special machine for tin ore and wolframite ore separation and purification, intensity will be high between 8000guess to 28000guess adjustment. People will adjust magnetic induction intensity, reaching a one-time separation of various minerals; the operation is very easy and efficient.

Currently it is the most commonly and widely used in tin ore and wolframite ore separation industry.
