Fig. 1 provides an illustrative flowsheet of the traditional process used for producing chromic oxide (Cr 2 O 3) from chromite ore.During the initial stage, insoluble chromite ore is converted into water-soluble chromate. Roasting a mixture of chromite ore, sodium carbonate (Na 2 CO 3), limestone, and dolomite at 1100 °C for several hours …

Conclusions1.On the basis of new investigations of the chromium-boron system and of a consideration of the literature data there is proposed a more plausible diagram of state of the system.2.There has been confirmed the absence of the compounds Cr4B, Cr2B with a structure of the type CuAl2, Cr3B2, and CrB6.3.For the compound Cr2B, with a Mn4B …

The chromium (Cr) content of stainless steel originates from recycled scrap and/or ferrochrome (FeCr), which is mainly produced by the carbothermic reduction of chromite ore.

Platinum Group Metals (PGMs) are recovered through underground and open pit mining from poly-metallic sulphide ores containing PGMs, Nickel, Copper and other metals: • Platinum (Pt), Palladium (Pd), Rhodium (Rh) and Ruthenium (Ru) are the most prevalent of the six PGMs, with Iridium (Ir), and Osmium (Os) found in much smaller quantities

Nickel processing - Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating …

chromium(III) oxide derived from this process may then be used as raw material for the manufacturing of chromium chemicals, stainless steels, chrome metal or other chromium-containing alloys. The proposed flowsheet and the fundamentals of the different stages of the process are discussed in this manuscript. EXPERIMENTAL
