Heap Leaching of Gold and Silver Ores - ScienceDirect
2016-1-1 The operating cost plus debt service for a medium-sized mill (3000 t/d) is typically $39/t of ore treated, whereas the comparable cost for the heap is $19/t, equating to a differential operating cost plus debt service of $20/t for milling compared with heap leaching. Assuming a gold price of $40/g ($1244/oz), the differential cost would require the milling option to deliver an additional 0.5 g/t of payable gold from the extra 25% gold recovery compared with the heap leaching

MIT Western Hemisphere Project: Cyanide Gold
The leaching technique was used in small measure by miners in the early 1900s to draw gold and copper out of ore so low in mineral content that large-scale operators would have tossed it out as waste. In the old days, leaching was done by misting cyanide over a barrel or large vat filled with crushed ore.
