Coastal sand mining of heavy mineral sands: Contestations, …
The Australian mineral sands industry witnessed the next boom in 1951 with the start of the Korean war in 1950. By late 1951, the price of rutile increased to 140$ per tonne, as compared to 47$ in 1950, which led to a doubling of production from 18,606 tonnes in 1950 to 35,754 tonnes in 1952 (Morley, 1981).
Land degradation and rehabilitation in coastal sand mining
Later mineral sand mining focussed on the heavy minerals, rutile, zircon, ilmenite, and monazite (Morley, 1981). Rutile and ilmenite contain titanium, which is mainly used in the form of titanium dioxide (TiO 2 ) as a white pigment in paints, plastics, paper, and other products that require a bright white pigment.
Attrition Scrubber | Attrition Machine | Attrition Cell | Silica Sand …
Attrition scrubbing is the process where a mineral is scrubbed primarily by the action of the slurry particles impacting one another. Attrition scrubbers, also known as Attrition Cells, are relatively simple devices. They consist of a tank, impeller system and drive system. Generally, the tank is PE lined and can be either square or octagonal.
