ABSTRACT IMPROVED LEACHING PROCESS FOR METAL ORES The general overall sequence of process steps in the technique of the invention is set forth in Fig. 1. In sequence, the ore is crushed, and solubilizing reagents and moisture are added to the crushed ore in preselected controlled portions. The mixture of ore, reagent, and moisture is then cured followed in the preferred process by conditioning for filtration. The slurry that is pro- duced from conditioning is then subjected to multiple stage washing on a belt filter. The filtrate is further processed for metal value recovery and the solids are transported to tailings disposal.
