Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

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.

Extraction of diamonds into a concentrate results in recovery of 96 percent of the diamond content of the ore. The most widespread method for recovery of diamonds from concentrates is the greased-table process, based on the selective ability of diamond to stick to greasy surfaces (suggested by F. Kirsten in 1897).

In the ore, the core recovery is small. Half the split core, or often a few representative pieces, are placed in the tin box with a sample of the sludge and the end of the box is properly labeled. A representative sample of the hard rock above the ore is kept also in the tin box. By this method samples can be stored in a relatively small space.
