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.

Diamond Mining Methods Diamond Museum Cape Town
The first diamonds discovered in South Africa were from alluvial deposits. Today, industrial alluvial mining involves building a large wall to collect the water in one area. Diamonds are often found in the gravel layer, which collects under layers of other material, such as mud, clay and underwater plant-life.
