Heap Leaching Basics
Heap Leaching Flow Chart Incorporating Agglomeration into the Heap Leaching Process. The agglomeration of the fines in the heap leaching process allows for enhanced, even percolation of a heap. If left untreated, smaller fines can accumulate in the spaces between larger particles, inhibiting flow of the leaching solution (see figure 2).

About Us
Water is also added, which turns the ore into a slurry. We send this slurry to leaching tanks, where we add a weak cyanide solution to the slurry, which leaches gold and silver into the solution. This process removes up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution.
