Abstract
Abstract
| This paper describes a fundamental approach to in situ leach mining (ISLM) lixiviant development which emphasizes leaching selectivity through detailed characterization of mineral-solution interfacial chemistry and post-leach geochemistry. This experimentation and modeling approach consists of: (1) petrographic identification of reactive ore and gangue minerals; (2) determination of leaching kinetics of individual minerals through batch leaching tests; (3) evaluation of bulk solution geochemistry through column leaching tests; and (4) ISLM simulation of element species transport and geochemistry through core leaching tests. Recent results confirm good leaching selectivity for manganese, but reveal post- leach precipitation and permeability loss during core leaching experiments. |
