Studies on flocculation characteristics of chromite’s ore
The chromite ore beneficiation plants are present in this region. The beneficiation plants majorly consist of comminution to physically liberate the minerals ore beneficiation, specific gravity and size-based separations are the most convenient and cost-effective methods [3, 4]. Chromite tailings ore sample was obtained from a MG chromite processing plant in the Western Limb of the Bushveld Igneous Complex (BIC), South Africa.

Recycling of Chrome-Containing Waste from a Mining and Processing Plant
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 The chromite ore beneficiation plants are present in this region. The beneficiation plants majorly consist of comminution to physically liberate the minerals followed by physical separation to generate the concentrate. During the comminution process, large quantities of fines generated. The fines commonly de-slimed using hydro Studies on flocculation characteristics of chromite’s ore

Improving the Quality of Ferruginous Chromite Concentrates Via Physical
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 For instance, beneficiation plants in Sukinda, India, reject large quantities of low- and sub-grade chromite ores It is shown that during the beneficiation of chromite ore, significant volumes of value-containing tailings (in the form of rejected chromite) are generated.

Superficial fresh chromite tailings and concentrate ore, as well as a core in the stockpiled old chromite tailings, were collected in May 2017 from materials generated in a typical beneficiation plant of Sukinda valley, Jajpur district, Odisha, India . The Sukinda valley is located in the eastern part of the Indian peninsula, where the averageAs seen in Fig. 11.8, imported chromite is sent to smelters, chemical plants, and refractories, through either direct sales or domestic beneficiation plants. Beneficiation begins with the milling of mined run of mine (ROM) ore to make the ROM ore suitable for further activities to recover Cr values.Chromite ScienceDirect
