Characterisation of Tailings from Itakpe Iron Ore Mine

At the Itakpe iron ore mine, the ratio of waste to ore is 4:1. The ratio of tailings to concentrate is commonly very high, generally around 200:1 [6]. For instance, it has been reported that in Western Australia, on average, the production of 1 tonne of iron ore results in the generation of 2 tonnes of iron ore …

Efficient utilization of nickel rich Chromite Ore

Sep 15, 2021 1. Introduction. Chromium finds diverse application in the refractory, pharmaceutical, metallurgical and casting industries (Aljerf, 2018; Tathavadkar et al., 2004).Among 82 distinct ore forms of chromium as an element, chromite (FeCr 2 O 4) is the only form that is extracted at a commercial scale (Motzer and Engineers, 2004).Chromite belongs to a spinal group of minerals represented by …

Thermodynamic estimation on the reduction behavior of iron

The thermodynamics for reduction of iron-chromium ore by carbon is discussed. The thermodynamic properties of iron-chromium ore were evaluated from our previous work on the activities of constituents in the FeO Cr 2 O 3-MgO Cr 2 O 3-MgO Al 2 O 3 iron-chromite spinel-structure solid solution saturated with (Cr, Al) 2 O 3, and those of the Fe-Cr-C alloy were estimated by a sublattice model.

Effect of Chrome Ore Quality on Ferrochrome Production

3. METALLURGICAL BEHAVIOR OF CHROME ORE 3.1 Reducibility Reducibility of ore, as has been indicated before [1, 2], is determined by its mineralogy (MgO/Al2O3 ratio), the MgO structural form in the chrome ore, chromite grain size, the extent of grains distribution in ore and the ore melting temperature.
