Production | Newmont Goldcorp Lifecycle of a Mine
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 recovers up to 93 percent of the gold and 70 percent of the silver from the ore. Carbon granules are then added to the solution. The gold attaches to the carbon and is pulled from the solution.

Agglomeration Drums in the Heap Leaching Process
Heap leaching, a process by which metals such as gold and copper are recovered from ore, has long been a method of choice in ore beneficiation, with applications growing all the time.. While this process has proven to be efficient, often chosen for its costeffectiveness, the efficiency of the heap leaching process can be further improved through the addition of an agglomeration drum.
