Low grade ore is often processed using a heap leach process. Heap leaching involves crushing the ore to <3/4" (<19mm) diameter chunks and piling on a punctureproof liner. The liquid cyanide solution is poured over the heap and allowed to percolate down through the ore. The gold containing solution (pregnant leach) is collected from the liner into a leach pond and sent off to carbon ...
