Resource Intensity Trends in the South African
metals industry was identified as a major development, with chromite ore intensity decreasing from 2.54 to 1.98 kg per kg ferrochrome. Electrical energy intensity was observed to decrease from 3.47 to 2.86 kWh per ton ferrochrome, mainly as a result of cleaner smelting technology, thoughand lower operating costs. Keywords: chromite, beneficiation, spiral concentrator, teetered bed separator 1. Introduction The beneficiation of chromite (Burt 1984; 1999) and processing of its low-grade ores (Ağaçayak, 2004; Amer and İbrahim, 1996; Sönmez and Turgut, 1998) are traditionally performed using gravity concentration methods.Developing an optimum beneficiation route for a low

Value of mineral deposits associated with mafic and
Magmatic ore deposits associated with ultramafic and mafic magmatism (MODUM) include nickel sulfide deposits that are locally enriched in copper, cobalt, platinum group elements and gold, a diverse range in platinum group element deposit types, oxide- and silicate-related nickel–cobalt laterite deposits formed by weathering of ultramafic The metallurgical grade chromite used in the production of alloy steel contains 48% Cr 2 O 3. The chemical grade chromite ore with a Cr 2 O 3 content of over 44% can be used in the production of sodium dichromate. Refractory grade chromite has a low (30-40%) Cr 2 O 3 content (Gu and Wills, 1988). There are two groups of chromite de-Investigation of chromite ore beneficiation possibilities

Improving the Quality of Ferruginous Chromite Concentrates Via Physical
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the oxidized chromite production cost of R893.01 per ton OC and a FeCr production increase of 29 523 t /a, the DCF model yielded an NPV of approximately R895 million with an IRR of(PDF) Techno-economic feasibility of a preoxidation
