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

Efficient utilization of nickel rich Chromite Ore Processing

To enrich the chromite values, researchers have treated the COPT in the different dry and wet beneficiation processes, and the summary of these studies are listed in Table 1.Most of these enrichment routes are stated to produce a marketable chromite-rich concentrate, but it generates more ultrafine tailings, which is again a waste for industry Also the efficiency of chromite beneficiation for magnetic and shaking table tests was changed between 40-70 %.

Efficient utilization of nickel rich Chromite Ore Processing

In the present study, the tailings generated from a chromite ore beneficiary plant in India were investigated through a pyro-metallurgical route. The initial characterization confirmed the presence of nickel (0.5–0.9% Ni) in the ore, which led to the interest in smelting the ore to obtain nickel in the metal.The recovery of chromite from the tailings streams of South African UG2 platinum concentrators adds significant financial returns to these operations.
