How are diamonds separated from ore? - DMS Powders

There are different stages when analysing the diamond separation process. Underground mining methods involve the blasting of ore, to be removed from under the ground. The ore is collected and brought to the surface for processing. Once the ore is retrieved, the diamond processing begins. The different phases in separating diamonds from ore include:
