Hard Rock Mining Applications. Hard Rock miners around the world have historically recovered as little as 30% of their free gold using mercury amalgamation. The iCON process is being used to scavenge/reprocess old tails without using mercury. These miners are now recovering more gold reprocessing tails with iCON than the original miners recovered.

Historically, hard rock gold mining has been extremely important in the USA, Australia and indeed across the world. While placer gold was man''s first gold discovery and his first source of gold metal, the in place resources of the rocks have come to yield a higher production as placers are all too quickly mined out.

Free gold is the portion that is easily removed without the use of complex chemical procedures. Miners have been extracting free gold from hard rock sources for thousands of years. It simply requires that the ore be crushed and broken apart enough that the gold can be separated from the host material.

It was underground, hard-rock mining operations that transformed California gold mining into a corporate activity. It was in the Northern Mines, clustered around Grass Valley, which dominated underground mining. In the beginning, the gold-bearing quartz was wrenched from underground veins by backbreaking, dimly lit sweat and blood.

Hard Rock mining operations may have 100 grams of gold per ton of feed. This is very rich. In this case it is common to run for only 10 minutes between rinse cycles. You may choose to feed at ½ ton per hour. When upgrading concentrates you will be processing rich and heavy material. In this case the cycle time may also be only 10 minutes.
