Diamonds and other precious and semi-precious gemstones are extracted from the earth via three main types on mining. These diamond extraction methods vary depending on how the minerals are deposited within the earth, the stability of the material surrounding the desired mineral, and the peripheral damage done to the surrounding enviroment.

A Patented design with inter-connecting apertures and alternative solid dams of different thicknesses make the screen panel non-pegging and non blinding

These cyclones couple the highly efficient Multotec scrolled evolute inlet design with an engineered tile wear surface, thus ensuring MAXimum efficiency of separation and MAXimum wear life. The MAX range of cyclones embodies the considerable specialised technological expertise and experience of two companies, Multotec Process Equipment and Multotec Wear Linings.
