Fluor has executed more than 40 different diamond projects for major Clients worldwide including diamond process facilities in Australia Botswana Canada and India The majority of the diamond processing plants designed by Fluor are based on the dense medium separation DMS principle coupled with Xray sorting which generally provides the most efficient diamond concentration technique

Comminution and Liberation Before a diamond is even processed it must be mined first The mineral is recovered from ore through a process known as comminution and liberation Comminution is the breakage of larger ore into smaller particles The liberation is the process of removing the incorporated diamond from the ore

Diamonds are also mined from the seabed using horizontal and vertical marine mining De Beers mines diamonds from depths of 90 14 meters In horizontal mining a crawler uses flexible hoses on the ocean floor to bring diamonds to the surface In vertical mining a largediameter drill allows for greater depth and brings diamondbearing gravel to the surface
