2011-4-1 To recover these fines, investigation results of Feng and Aldrich (2004) on the Western Chromite Mines in South Africa, shows that maximum 95.6% of chromite fines can be recovered by using column flotation with the optimum conditions of parameters. Flotation recovery of many minerals decreases as the particle size decreases.

2004-3-1 The chromite was obtained from a gravity concentration process supplied by the Western Chrome Mine in South Africa. Its chemical composition was 51.8% Cr 2 O 3, 29.20% Fe 2 O 3, 8.27% MgO, 7.67% Al 2 O 3, 2.23% SiO 2 and 0.79% CaO. The mineral was ground to 100% −75 μm in a pebble mill and stored in an air-tight plastic bag.

TREATING CHROME TAILINGS FOR PGMs -
2008-8-19 The process at Millsell involves six stages, the first of which is the obviously the mining that produces the tailings. The mines, in upgrading the chromite content of their ore, produce a tailings stream that contains the majority of the PGMs of the ROM chrome ores. It is these chrome ores with elevated levels of PGMs that are treated.

Recovery of chromite fines from wastewater streams by ...
In column flotation tests for the fresh wastewater stream containing 3% chromite fines, a recovery and grade of approximately 40% and 43.5%, respectively were obtained with sodium dodecyl sulphate (SDS) flotation. A recovery and grade of approximately 32% and 45%, respectively were obtained with cetyl trimethyl ammonium bromide (CTMAB) flotation.

2022-1-4 Flotation. Background. Froth flotation is the follow-on operation, after comminution and classification, in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore. Froth flotation is achieved when particles are separated based on their surface potential.

Chrome Ores on Ferrochrome Smelting
2015-3-12 Abstract—Chrome ores from six locations across the Bushveld Igneous Complex in South Africa are used to investigate the effects of ore types on the smelting processes, such as the consumption of fluxes, reductant; and most importantly, the consumption of electricity. The electric energy consumption is highly related to the SiO 2
