Abstract
Experimental results obtained from large-scale (7 tons), long-term (500 days) leaching of low-tenor copper sulfide ores were interpreted by a geometric model involving the movement of a reaction zone through the ore fragments. The postulated leaching mechanism involved mixed kinetics and included diffusion of the reacting species through the host rock and a chemical reaction at the surface of the mineral particles. Ore properties that were considered were ore particle size and shape, grade of ore, and mineral content.
