Maximisation Of Chromium Content Of Ferrochrome In Dc Arc

Maximisation Of Chromium Content Of Ferrochrome In Dc Arc

Jul 18, 2013 AbstractDC arc smelting is one of the recent techniques to smelt fine ore particles. First time in the world, Indian chromite ores were smelted in DC arc furnace in Pilot Plant of Mintek, South Africa, to produce high carbon ferrochrome (HCFeCr). Major objective was maximisation of Cr content in HCFeCr. Investigations include factors influencing chromium content, interdependence of C, Si and.

Leaching Of Hexavalent Chromium From Young Chromite Ore

Leaching Of Hexavalent Chromium From Young Chromite Ore

Mar 18, 2020 Chromite ore processing residue (COPR) is a waste derived from the chromate extraction from roasted ores and is deposited in some countries in landfills. The objective of this study was to investigate the leaching characteristics of hexavalent Cr [Cr(VI)] from two COPR samples obtained from unlined landfills in the Kanpur area of northern India.
