magnetic separation studies on ferruginous chromite fine

Mar 04, 2015 · The Cr:Fe ratio (chromium-to-iron mass ratio) of chromite affects the production of chrome-based ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the application of magnetic separation to fine chromite from the Sukinda region of India to enhance its Cr:Fe ratio has been reported

Those countries and areas are often developing and underdeveloped countries and areas in which serious environmental pollution issues accompany intensive mass production

Jul 01, 2012 · 1. Introduction. Chromite ore mining is the only commercially viable source of new chromium units (Murthy et al., 2011, Beukes et al., 2010, Cramer et al., 2004).South Africa holds approximately 75% of the world’s exploitable chromite resources (Basson et al., 2007, Cramer et al., 2004, Riekkola-Vanhanen, 1999), with other smaller but substantial deposits occurring in Kazakhstan, …

South Africa holds approximately three-quarters of the world's viable chromite ore resources and dominates the global production of ferrochrome. Albeit completely unintended, small amounts of Cr(VI) are formed during ferrochrome production. ... MURTHY, Y.R., TRIPATHY, S.K., and KUMAR, C.R. Chrome ore beneficiation challenges and opportunities

This study aimed to evaluate the chromite recovery from shaking table tailings of Forumad plant by a dry high-intensity magnetic separation. The average feed grade of chromium trioxide (Cr2O3) was 7.62% by XRF. Also, different mineral phases were determined by XRD, identifying the presence of Chrysotile, Augite, Albite, Chlorite and Chromite

Slags coming from stainless steel (SS) and ferrochromium (FeCr) production generally contain between 1 and 10% Cr, mostly present in entrapped metallic particles (Fe–Cr alloys) and in spinel structures. To recover Cr from these slags, magnetic and gravity separation techniques were tested for up-concentrating Cr in a fraction for further processing. In case of SS slag and low carbon (LC
