How to choose skarn type tungsten ore?

Laterite ore is a loose clay-like polymer containing nickel oxide, iron oxide, chromium oxide and other elements. Because the ferric iron element rich in it is reddish brown, the overall color of the mine is also reddish brown, that is, laterite mine.

After the laterite is mined, it needs to be beneficiated. Generally, a combination of gravity separation and magnetic separation is used to purify the chromium ore in the laterite:

① Crusher and ball mill are used to crush and grind the raw ore, and the sieved particle size of the processed mineral is 200 mesh.

② The crushed and ground ore is introduced into the hydrocyclone for classification. After classification, the underflow part returns to the crushing and grinding process for secondary grinding to form a closed loop. The overflow part is transferred to the spiral chute for water washing. The flow rate is 9L/min, and the washed ore is divided into heavy and light products. The heavy products enter the next stage, and the light products are discharged as tailings.

③ Roughly select the heavy ore by means of a shaker to obtain rough concentrate and tailings.

④ Use a wet-type drum magnetic separator to select and purify the rough concentrate to obtain qualified chrome concentrate.
