Efficient utilization of nickel rich Chromite Ore Processing Tailings by carbothermic smelting

Chromite ore processing tailing, a solid waste generated during the of chromite ore, is difficult to recover due its ultra-fine size. The tailings from process contains valuable and iron-bearing minerals, loss which matter concern for ferrochrome industry worldwide. Tailings plant mainly dumped, causing space environmental concerns. Researchers worldwide have carried out rigorous study on recovery tailings, considering low quantity Cr(T) Fe(T) in ore. These processes are partially successful further assimilation form tailings. In present study, beneficiary India were investigated through pyro-metallurgical route. initial characterization confirmed presence nickel (0.5–0.9% Ni) led interest smelting obtain metal. behaviour studied under submerged arc furnace blast condition, varying basicity. A cost economic analysis evaluated understand feasibility real-time operation. investigation has revealed that such could result metal product with 79.23% Fe(T), 12.94% chromium 1.11% >94%. produced slag enriched higher amorphous phase glassy >89%. suggested cleaner sustainable approach towards valorisation mining realization concept circular economy. It concluded carbothermal enrichment can be valorized route at optimum basicity 1 by promoting zero discharge.
