It is estimated that 18–25% of tailings are being generated during the processing of iron ore. The major compositions of iron ore slime are hematite, goethite, quartz, alumina, mica and kaolin (Roy and Das 2008). The iron ore slime is discarded due to its particle size and chemical composition which are not suitable as feed to the blast furnace.

Testwork was undertaken to develop a flowsheet that would maximise gold recovery from an ore containing 3 g/t Au and high levels of arsenic. Treatment of the sulphide ore involves gravity separation, flotation, and cyanide leaching. A gravity concentrate is recovered within the grinding circuit before the ore is subjected to froth flotation.
