The mill used a system of physical separations to crush, concentrate, and amalgamate the ore. The final smelting used a system of chemical separations. It is a perfect example of a chemical engineering process, and was continually upgraded and improved during its 61 years in operation.
The methods mentioned so far are all physical separation methods. Sometimes they are sufficient to separate minerals for use, like coal or iron ore. But more often the element that we are looking for is found as a chemical compound, and so will have to be separated by further chemical reactions. For example, copper in Cu 2 S or aluminium in Al 2 O 3.
South Africa’s andalusite industry was founded on work done at Mintek. More recently, dense-media separation has been incorporated into platinum-group metals flowsheets, to separate barren waste rock from ore prior to milling.
