alluvial diamond mining process

Diamond Mining Solution - Mineral Processing

Alluvial Deposits Diamonds Mining are recovered from ore in 5 stages: Stage 1 – Crushing. Once the diamond bearing ore and gravel is collected, it is transported to a primary crusher. The primary crusher is responsible for reducing the size of the ore into smaller, more manageable pieces or chucks measuring no larger than 150mm.
