This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore -0.074 mm going to froth flotation cells for recovery of iron. In magnetite Processing plantthe Process of flotation separation is replaced by magnetic separation.

For example a tailings stream in an iron ore appli ion could be thickened to 45–50% solids Newtonian slurry in conventional or high-rate thickeners. Conversely the same tailings stream could be thickened to 65–70% solids non-Newtonian suspension using a paste thickener.
Iron tailings contained up to 76.7% silica and 15.77% iron oxide along with other major components such as alumina 1.95% calcium oxide 1.48% and magnesium oxide 2.93% . The particle size distribution of the iron tailings showed that most of the particles were distributed under 1 mm accounting for about 73.8% and 40% of the particles
Amankwah et al. 200535 performed tests on samples of a gold ore containing quartz sili es and iron oxides with a head grade of 6.4 g/t of gold using 2 kW of power in a multimode cavity. It was seen that the microwave treatment resulted in a maximum reduction of 31.2% in crushing strength and a reduction of 18.5% in work index.
The iron ore tailings consist of a moderate amount of various heavy metals e.g. copper iron manganese lead zinc and a lower level of macronutrients. A few living organisms have been found

1. Introduction. Since the discovery of the supergiant Olympic Dam deposit in Australia in 1975 Iron Oxide Copper–Gold IOCG deposits have become the largest producer of uranium Hitzman and Valenta 2005 Skirrow 2011 the third producer of copper Sillitoe 2012 and significant producer of gold Kerrich et al. 2000 Frimmel 2008 Porter 2010 .
Iron oxide copper–gold IOCG deposits contain economic or anomalous gold and the gold distribution is important both for its economic significance and ore genesis. However the gold distribution in IOCG deposits and its controlling factors remain unclear. The gold grades and tonnages of selected thirty-six deposits in some well-defined IOCG provinces are compiled in this paper. The gold
