Introduction: This mobile jig concentrator is very popular in small-scale gold, diamond, and coltan processing plants. The trommel screen sieves out big waste stone firstly, and then the under-sieve material goes to the jig concentrator for gravity separation. The heavy mineral would be collected at the final.
