Introduction. The world supply and reserves of chromite or chrome ore (FeCr 2 O 4) have been dominated mainly by South Africa and the ex-USSR, which made chromite a strategic material in many Western countries [1].Bhappu highlighted the need for more research into the processing of low grade refractory ores of strategic metals such …

In the Western Chrome Mine in South Africa, the process water stream contains approximately 3% chromite fines (< 100 mum), which report to the tailings dam. This results in resource loss and water ...

While this staged process increases overall recoveries, overgrinding may occur, hence creating problems associated with fine particle flotation. This paper presents an overview of the mineralogy of …

This research work focused on the impact of residual flocculant on flotation performance of Platinum group metal (PGMs) ores in terms of recovery. The impact of residual flocculant on PGMs recovery using recycled process water from a chrome processing rougher plant was investigated. Water samples from the flotation circuit and chrome plant were ...

In the South Africa installations, the wear on the rotors and stators has been minimal after more than a year's operation, the company says. In one flotation cell, the equipment has been operational for 15 months. The thickness of the rotor has reduced from 65 mm to only 60 mm, and the stator from 75 mm to 70 mm.

2016). This is particularly relevant in South Africa, which is the biggest global producer of platinum, gold and chrome (Mohale et al., 2015). An aspect which is often overlooked in the life cycle of sustainable mine residues management, and which can resolve, at least partly, these challenges, is

About 80% of the worlds' reserves for platinum group metals (PGMs) are in South Africa's chrome content in the feed and the challenges associated with operating high chrome been commercialised.

In the Western Chrome Mine in South Africa, the process water stream contains approximately 3% chromite fines (< 100 mum), which report to the tailings dam. This results in resource loss and water ...

proportion consumption of chrome ore in the metallurgy industry accounts for more than 80% [1, 2], and With the rapid development of stainless steel industry, this proportion will further increase [3]. In China, the chrome ore is mainly imported from South Africa, Turkey, Iran and other countries. In recent years, the proportions M.-F. Ye (&) G ...

The use of the AOD process has allowed lower grade (hlgh-iron 'charge chrome') ores to be used in steelmaking as well as the traditional high-chromium, 'metallurgical grade' ores. This development is the main reason for the expansion of the chromite mining industry in South Africa, the high-iron stratiform deposits being …
