The Effect of Bio-Coal on the Carbothermic Reduction of Laterite Ores
MATERIALS TRANSACTIONS, 2015 In order to investigate the effect of bio-coal on the carbothermic reduction of laterite ores, carbothermic reduction experiments of two type laterite ores mixed with bio-coal were conducted in this research. The reduction experiments were carried out at 11731673K for 1800s in Ar.
