Coltan beneficiation equipment, coltan enrichment machine, how to improve coltan ore

coltan content is usually low with its big specific gravity and weak magnetism, and the composition is complex.

Coltan content is usually low and the density of TaNb mineral is big while the magnetism is weak. So there are many beneficiation methods for TaNb enrichmentand its processing is complex. The main beneficiation mainly covers gravity separation, magnetic separation, electric separation, and floatation separation while sometimes hydrometallurgy will be involved. Rough separation and fine selection will be needed to get high grade TaNb mineral concentrate. 

At this moment, the main beneficiation way for coltan ore is gravity separation with its lowest plant investment. However, for the micro fine inlay coltan ore, the efficiency will be not so good while the recovery rate is low. Plants of jigging machine, spiral washing machine, shaking table, and centrifugal separator are involved in gravity processing line for coltan ore.

For some uneven inlay TaNb mineral separation, the raw ore shall be crushed t be 10-15mm, and the rod mill will be involved to to make the ore to be -2mm, and then the output from the rod mill can go for jigger for rough separation. Then the shaking table will be involved to upgrade the concentrate from the jigger furtherly. The tailings from the shaking table can go for spiral washing machine to get the coarse grains of TaNb and the concentrate from spiral washing plant can be upgraded by shaking table. And final coltan concentrate can be gained.
