Iron Precipitation Strategies from Nickel Laterite Ore …
Iron removal higher than 99% was obtained at pH 2.5–3.3, with metal losses of up to 1.8%. In the second step, milk of lime (1.5 CaO g/100 mL) was used as a reagent. A final solution containing only 2.1 mg.L −1 of iron, with nickel and cobalt losses below 1.6%, was achieved at pH 3.7–3.8; the precipitate was identified as bassanite. The ...

Traditionally, for minerals, applications have included pre-grinding or re-grinding in iron ore pellet feed preparation circuits, or as secondary or re-crushing devices in Kimberlite processing. In the latter case, the unit was introduced in the re-crushing of DMS product, but effectively operated as open circuit unit ( Maxton et al., 2002 ).

The estimated greenhouse gas emissions were 11.9 kg CO 2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions from the mining and processing of iron ore.
