Minerals mined in Australia include iron ore, coal, gold, copper, nickel and zinc. ... In this process, a slurry of crushed ore is placed in a vessel such as a shaker table, spiral concentrator, or jig designed to facilitate mineral separation based on density. The specific gravity of a mineral is the ratio of its density to that of water.

In the Coons-Pacific Concentrator two distinct types of waste were produced - tailings and waste rock. The tailings at the Coons-Pacific Concentrator were those fine materials that overflowed in the concentrating sections, as they happened to be lighter and less dense than the concentrated iron ore.

Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
