Spiral technology is ideally suited to the recovery of Middle Group (MG1, MG2) and Lower Group (LG6) chromite ores, which are the richest chromite seams of the Bushveld Complex. Menzi Xulu was sponsored by Mintek to do a chemical engineering degree at the University of the Witwatersrand, so he began his career doing research and development ...
The hydrosizer feed in the studied circuit (Fig. 1) is the middle product of the shaking tables with an average Cr 2 O 3 grade of 17%. The feed is classified based on the specific gravity and the liberation degree of particles. Outputs of spigots 1 and 2 are introduced to two separate spirals, and the output of spigot 3 is introduced to a shaking table due to the fact …

The chemical composition of the chromite tailings sample is shown in Table 1. Table 1 shows that the sample had a chromite content of 20.03% with silica as the major gangue measured at 33.50%. The iron oxide content assayed at 17.94%. The chromite content corroborates the research that was conducted by [4] which indicated that there is sufficient

Most of the heavy minerals including chromite are treated in gravity concentration at different stages of upgradation [9], [10]. The popularity of gravity concentration is due to their simplicity, low operating cost and ease of operation. Spiral concentrator is the key operating unit and is widely used for concentrating different minerals and coal.
Traditional spiral concentrators used to treat finer material had lower separation efficiencies, grades, and recoveries. The M10A tail had a chromite content of 12.92%, the M10B tail had a content of 11.48%, and the M50 tail had a content of 14.50%. When compared to M10A and M10B spirals, the M50 spiral recovers more chromite to the tailings.
Chromite smelting slag processing line is mainly to recover the chromite alloy from the chrome smelting slag. For this processing line, not only the smelting alloy can be recovered, but also the final slag can be recycled. more than ninety per cent of …
This study focuses on examining the separation performance of spirals employed in a classified fine-sized (− 200 + 2 5 µm) chromite ore. Dwindling global reserves of high-grade chromium ores and dispersing minerals in the form of fine particles make it attractive to find alternative and efficient methods for enriching these minerals in an economically as well as …

As the splitter position moves away from the centre of the spiral axis, the concentration of chromite increases which in turn increases the recovery (Mishra and Tripathy, 2010) and as there is an increase in the pulp density, recovery …
with inland examples in the Murray Basin. Chromite deposits are rather rare in Australia, mainly because of the lack of large layered intrusions of Bushveld proportions, although thin chromite seams are mined from Coobina in the Marymia Dome of WA. Australia is a relatively small but significant nickel producer on a world scale.
