About Atoll Metal Recovery, Dr. Peter Scott,uranium

2019-1-22 · Atoll still operates the plants in Sweden, Romania, Turkey and the USA as well as one plant in RSA. The other plants have been sold to the slag owners. Although metal from slag recovery remains a key focus, Atoll is turning more of its attention to the beneficiation of minerals by jigging, particularly manganese and iron ores and coal.2016-1-1 · Ferrochrome is made by smelting chromite ore in an electric arc furnace with flux materials (quartz, dolomite, limestone, and aluminosilicates) and a carbonaceous reductant (wood chips, coke, or charcoal) (Kleynhans et al., 2012, USEPA,). The solid products obtained from smelting ferrochrome are metal, slag, and dust.Chromite ScienceDirect2010-1-5 · chrome ore is very readily reduced in solid state before it is melted, resulting in a Cr2O3 content in the slag of 1.5 – 4.0 percent. Also of significance is the complete separation of metal and slag during tapping and casting due to the low viscosity of the slag [1, 5], thus the losses from this part of the operation is very low.Effect of Chrome Ore Quality on Ferrochrome Production
