Recovery of metal from slag/mixed metal generated in ferroalloy plants-a case study

Studies were carried out at R&D, Tata Steel to develop a flow sheet for the recovery of metal from metal-slag mix generated in its charge chrome (ferrochrome with 50-60% chromium) plant, Bamnipal. The studies showed that in the case of the charge chrome plant, crushing of mixed metal and slag to below 10 mm followed by jigging of the −10+1 mm material and tabling of the −1 mm material would help recover 10 tpd of metal from the 18 tpd of mixed metal. Based on the studies, a plant is now operational at the Ferro-Alloy Plant (FAP), Bamnipal which recovers ferrochrome metal from mixed metal and slag.
