December 2009; accepted 23 April 2010 Abstract: A novel treatment process of lead anode slime bearing high antimony and low silver was developed by a potential-controlled chloridization leaching... distillation residue. As a result, the recovery rate of Sb is more than 95%. Key words: lead anode slime; potential-controlled chloridization leaching; continuous distillation; antimony trichloride......

Effect of mechanical activation on alkali leaching of chromite ore ZHANG Yang(张 洋)1, 2, ZHENG Shi-li(郑诗礼)1, DU Hao(杜 浩)1, XU Hong-bin(徐红彬)1, ZHANG Yi(张 懿)1 1. National Engineering Laboratory.... It is observed that the extraction ratio reaches 97% after leaching for 200 min when chromite ore is mechanically activated for 10 min, but only 34% if not activated. Mechanical activation can decrease......
