Abstract

Ferro-molybdenum slags are by-product from ferro-molybdenum smelting industry. However, ferro-molybdenum slags include about 1 wt% molybdenum. Recycling ferro-molybdenum slags not only is valuable but reduces environment impact. This study focus on physical separation methods such as crushing for screening, grinding (ball mill) for classification and attrition scrubbing for concentration and expects to increase to 2 wt% molybdenum in slags. To find out the optima parameter (different particle sizes, leaching agents, contact time and liquid to solid (L/S) ratio) for leaching and to expect molybdenum leaching rate 95%(or more). In the future, depends on this study to develop a series of ferro-molybdenum slags recycling system.
