Chromite beneficiation plants generate large amount of tailings with significant amounts of ultrafine chromite minerals. In the present investigation, Box-Behnken experimental design was used tousing mechanical crushers. Crushed materials produced are usually below 10-14 mm (0.4 to 0.6 inch dia) so as to directly feed into the grinding milling machine. To get this grain size, crushing is done in stages. First few crushing is done using jaw crushers of upto 2 metre opening and the grain size is reduced to less than 150mm.INDUSTRIAL MINERALOGY: MINERAL PROCESSING,

Relationship between process mineralogical characterization
Process mineralogy of low-grade laterite nickel ore in Indonesia was systematically characterized and the beneficiation process of mineral components such as limonite, serpentine and chromite was studied on the basis of process mineralogy. The results show that the low-grade laterite nickel ore is a typical weathering sedimentary 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 Improving the Quality of Ferruginous Chromite Concentrates Via Physical

A chromite concentrate with 45.29wt% Cr2O3 and a Cr:Fe mass ratio of 1.85 can be produced from these low-grade chromite ore beneficiation plant rejects. Mineralogical characterization and liberation of valuable minerals are primary concerns in mineral processing industries. The present investigation focusesThe 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
