Leaching kinetics indicated that diffusion through the product layer was the rate controlling process during the reaction.Jan 01, 2016 This distinguishes heap leaching from dump-leaching. In dump-leaching, ores are stacked and leached in the most economical way possible, and success is achieved with any level of net positive cash flow. The bibliography of precious metals heap leaching is extensive, but a limited bibliography has been compiled at the end of this chapter. 1.2.
