The purpose of beneficiation is to concentrate the ore mineral physically and chemically suitable for subsequent applications. The gravity concentration is a well-established and widely accepted technique for chrome ore beneficiation due to the density difference between the chromite mineral and other associated gangue-bearing minerals.
Final tailings obtained from this process were having 40.68% Fe and can be rejected. 4 Conclusions The generation of iron ore fines in dry processing plant of Khondbond region, India is about 30–40% of the total feed.
Bauxite wet beneficiation requires large capital investments in a washing plant, tailings dams, power generation, water treatment, etc. and increased operating costs, environmental licensing, restrictions on water …
The beneficiation of iron ore slimes produced from washing plants and tailing ponds of Kiriburu mines was studied using wet high-intensity magnetic separators (WHIMS) followed by classification in hydrocyclone whereby a concentrate assaying 63% Fe and 3.3% alumina was produced with an overall iron recovery of 56% [9].
In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator ...

This paper systematically investigated the leaching behavior of bauxite li-thium-rich beneficiation tailings in caustic solution, together with their phase and morphological changes.
Another common problem in many chrome ore beneficiation plants is the presence of fine silicate gangue phases which contaminate the final concentrate. This variability affects the overall performance of the plant in terms of grade, recovery, and throughput, including losses of valuable materials into the tailings.
Gold tailings treated using multistage magnetic beneficiation and cementing filling can help ensure the clean utilization of all components of gold tailings and is expected to achieve tailing-free production, not only improving the comprehensive utilization of tailings but also alleviating the adverse effects of gold tailings on the …
This particular magnetic separator was also incorporated in the process flow sheet for upgrading the chromite fines while recovering from Indian chromite beneficiation plant tailings [8].
The general beneficiation process in these plants consists of gravity unit operations such as Floatex density separator, spiral, wet shaking table etc. Most of these gravity circuits suffer huge losses of valuable minerals in the tailing.
The specific beneficiation process employed depends on the characteristics of the iron ore and the desired iron content. Beneficiation plants are typically designed to handle specific types of ores and may vary in terms of …
This article reviews the major process flow sheets in practice for the recovery of chromite values from various types of ores and critical issues related to chromite ore beneficiation. Emphasis is placed on different processes developed in identifying and solving critical plant problems.
Studies on the composition and properties of tailings of the ore beneficiation factories indicate the prospects of processing them as a special type of technogenic ore raw materials.
Impact and anti-mechanical impact performance, used for power plant coal, ash, mine powder, tailings, backfill, coal in coal mines, beneficiation plants, coke particles in coking plants, and sintering plant materials.

In India, primarily, washing, jigging and classification are being carried out for the beneficiation of iron ores at coarse size range and in some plants spiral, magnetic separation and flotation ...
Tailing beneficiation of iron ore has been addressed either by flotation or wet high intensity high gradient separation. The present study aims to recover iron values from discarded slime containing assay ~56% Fe, ~6.5% SiO2, and ~7.0% Al2O3 from Noamundi processing plant by using high gradient magnetic separator (HGMS). In this …
The results of these plant trials, using a portable pilot plant set up, designed by TRDDC, are summarized in this paper. The slimes sample for these plant trials, was withdrawn from one of the slimes stream at the Tata Steel's iron ore beneficiation plant at Noamundi mines.
Animated video shows how accurate tailings samples are acquired through primary and secondary samplers in mineral beneficiation plants.
Other major costs for decreasing the silica content are capital costs for plants, manpower, maintenance, electricity and flotation reagent for ore beneficiation, and electricity for scrap upgrading.
The authors have also observed that one of the significant drawbacks of high-LOI low-grade iron ore beneficiation is the generation of tailings, which are considered one of the hazardous solid wastes and create disposal problems at the plant site.
Different types of beneficiation techniques are using for chromite ores to remove gangue minerals from the chromite concentrations such as gravity separation, flotation or magnetic separation (Kroll-Rabotin et al, 2013).

The detailed study of chromite ore beneficiation processes reveals that the opportunities still exist to recover chromite values from the low/sub-grade ores and tailings using the conventional beneficiation processes.
The plant, which will process live tailings produced by the independent Voyager (pictured) and Genesis plants, will ensure further beneficiation of the company's chrome production at the Tharisa Mine, while reducing unit output of carbon emissions, aligned with Tharisa's recently announced decarbonisation plan, the company says.
