This is a Diamond Processing Chart as it was done in the 1950s. World demand and production of diamond both for gem and industrial purposes has increased nearly five-fold during the past 25 years. Improved mining and recovery methods together with the discovery and development of new fields has enabled mining operations to fill the growing demands. Producing areas in Canada, South Africa
Beneficiation can begin with in the mine itself. Most mines will have a crusher within the mine itself where separation of ore and gangue minerals occurs and as a side effect becomes easier to transport. After the crusher the ore with go through a grinder or a mill to get the ore into fine particles.
Overview of a Diamond Beneficiation flow sheet: Ore from the primary stockpile is delivered to a scrubber, which removes clays and dirt, while high pressure grinding rolls crush the ore for screening. The ore stream is passed through both coarse and fine scrubber screens, wash and aid with classifi ion on the screens.
The beneficiation of diamonds is a direct result of the conditions required to be a DTCB sightholder 2 . One of the criteria is indeed that local processing should take place. Simply put, no processing, no access to rough diamonds. This policy required rough diamond traders to move down the value chain if they wanted access to rough diamonds.
There are basic principles and areas of importance within a diamond beneficiation plant that require focus and thorough understanding of the intended objective to ensure that optimum throughput and recovery are achieved by matching the appropriate interrelated unit processes.
The company expanded significantly in 2004 with the introduction of modular diamond plants to its range of process solutions. From 2004 to 2014 Consulmet developed from a single company to a group of companies, each with their own unique specialisations in mineral processing, metals recovery and engineering consulting.
SAFDICO’s diamond manufacturing plant is lo ed in the new Diamond Technology Park, lo ed between the airport and Botswana’s capital Gaborone. ‘High-tech’ is the phrase to describe SAFDICO’s diamond operation: computer-driven rough planners, laser bruters and robotic polishing machines.
