Ferrochrome (FeCr) is the main source of chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its corrosion resistance mainly to the presence of Cr. In turn, stainless steel is mainly produced from Cr-containing scrap …

Chrome ore beneficiation. Most of the chrome ores around the world are beneficiated by gravity concentration techniques. A conventional chromite ore beneficiation process plant (Figure 3) consist of two sections: > Communition (for preparing the material for the subsequent unit operations) > Concentration (classification and beneficiation).

Mineral Processing. Swapan Kumar Haldar, in Mineral Exploration (Second Edition), 2018. 13.2.4.3 In-Stream Analyzer and Process Control. Mineral beneficiation, particularly base and noble metals, is sensitive to optimum use of reagents, recovery of metals, and clean concentrate.High fluctuation of feed grade at flotation cells yields loss of metals to tailing.

India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the operations …

But heavy medium beneficiation or heavy liquid beneficiation is an effective method for spodumene beneficiation. For example, the mineral processing staff of the United States Bureau of Mines also used tetrabromoethane as the heavy liquid (density 2.9529 g/cm3) to carry out a continuous test of the heavy liquid cyclone separation of …

Beneficiation. An area where South Africa can increase its potential for economic growth, development and job creation is the Beneficiation of its extracted minerals. Beneficiation is the transformation of a mineral, or a combination of minerals, into a higher-value product, which can either be consumed locally or exported.

Raw materials were obtained from a large South African FeCr producer operating on the pre-reduced pelletized chromite process (Beukes et al., 2010, Kleynhans et al., 2012, Kleynhans et al., 2016) at two of their smelters.The sample materials, utilized on an industrial scale, consist of metallurgical grade chromite ore (<1 mm), bentonite …

A low-cost economic beneficiation process can help industries tackle waste disposal challenges. However, manganese ore shows vast variability in mineralogical characteristics and grades, which brings challenges to the selection and identification of suitable beneficiation processes for the ore [30, 31].
