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 …
Chrome has strong siderophilicity, and ferrochrome is often associated, also called chromite.Chrome ore beneficiation aims to extract chromium minerals from raw ore and remove impurities to obtain high-quality chrome concentrate. Generally speaking, chrome ore contains a certain amount of iron, so gravity separation and magnetic separation …
Prolonged development of ore deposits, ore beneficiation and metallurgical smelting of concentrates result in the accumulation of wastes, forming large-scale dumps and sludge ponds negatively affecting the environment and human health. The creation and introduction of industrial waste treatment technologies will make it possible to dispose of …
AlbChrome. For more than 20 years now, AlbChrome institutes one of the largest European chrome-rich resource management companies. Assets of the Company are: Chrome ore Mines, Metallurgic Plants, Processing and Enrichment Factories, Chrome Concentrate Factory, and other mining and metallurgy infrastructure elements, as a big part of the …
The aim was to identify all major gangue impurities, the degree of chromite liberation, and possible beneficiation options. The bulk material assayed 40.5% Cr2O3 with the major …
The specific kaolin beneficiation process needs to be selected according to the properties and requirements of the ore to realize the separation and purification of kaolin ore. JXSC will comprehensively consider factors …
Chromite tailings are generated from chrome ore beneficiation plants, containing substantial quantities of ultrafine particles. Generally these ultrafine particles of chromite cannot be treated effectively using conventional beneficiation methods, because of limitations in particles size being treated by these processes.
The conventional phosphate beneficiation process As mined, the phosphate and sand particles are embedded in compacted mud, or "clay-balls". Before separation can begin, all the particles must be liberated from the matrix of mud. The very first unit operation in the beneficiation process is to disaggregate the various particles; this ...
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 …
The critical issues related to the chromite process plants investigated by various researchers have been categorized as: 5.1. Reducing the tailing losses (9–20% Cr 2 O 3). 5.2. Beneficiation of low and sub-grade chromite ore (10–30% Cr 2 O 3). 5.3. Recovery of unrecoverable ultrafine chrome particles. 5.4.
