Hard rock deposits usually require blasting to excavate the ore, and crushing to extract it from the rock. A lone prospector with a gold pan can verify the presence of placer gold.
What is an Economical Heap Leach Mine Today As a rule of thumb, one gram per ton of ore can make a profitable heap leach mine.
