heap leaching dynamic

  • Heap leaching, as a dynamic process, was also considered for comparison to the column and in-situ leaching methods. This involves stacking of metal-bearing soil into a heap on an impermeable pad, irrigating it with a chemical solution for an extended period to dissolve the preferred metals, and collecting the leachate as it percolates from the base of the heap [27] [28].Flow analysis and dynamic slope stability in a copper ore ...The heap leach will be analyzed as a structure formed by six successive layers of 21m thick and two additional 0.75m layers for drain protection (Figure 3). The slopes have an inclination of 37°measured with respect to the horizontal and the base of the heap an inclination of 4.5% (Figure 8).HEAP LEACHING Experience-based approach to ... - SRKheap leach pad design H eap leaching has been applied to a number of different ores containing metals including gold, silver, copper, nickel, zinc and uranium. The ore can be processed as coarse rock, normally referred to as a dump leach, or as a crushed ore in a heap leach. The reagents used and the chemistry of leaching are metal
