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. A secondary crusher, known as a roll-crusher, may also be used to reduce the size of the ore even further.

The method of diamond mining you're probably most familiar with is called pipe mining. First, prospectors locate the primary sources for pipe deposits (in other words, where the diamonds are most likely to be found). Ore samples are then collected to evaluate the area. Then, shanks are inserted into the ground and soil is extracted.

The primary crusher handles what comes out of the mine. (Known as run of mine or ROM.) Then this material is fed into the secondary crusher to further reduce the size. The material is then further processed by the tertiary crusher. However, the material may continue to go through crushers to meet the desired size.
