100 TPH Alluvial coltan washing plant
2014/12/18 15:59:16

This process is designed by our engineer together with the customer's geologist, based on the size analysis and element analysis report.


  1 Considering there are many small stone which is over 50mm, we used a vibrating feeder with 50mm grizzly for feeding the material, and remove the big size stones.

  2 As the coltan particle size is under 30mm, we use a screen machine to remove the 30-50mm stones, and a 10mm layer to separate the remain material into 10-30mm and 0-10mm.

  3 The 10-30mm will goes to a cone crusher to crush the stones under 10mm; and then goes to the jig with the 0-10mm material.

  4 The jig get 0-2mm and 2-10mm different concentrate size, the 0-2mm concentrate will be processed again by shaking table.

  5 All the concentrate will be grinded by a ball mill and then dried for magnetic separation, to remove the iron inside and get the final product.


This project is already finished the installation, the commissioning will be taken place early of 2015, picture as bellow:
