Precious Metal Mining Techniques of Ancient Rome

Jun 25, 2014Once the gold veins were broken up, the area would become an open pit mine. Ore removed from the mine would be crushed by hammers powered by an ingenious water wheel. The resulting dust could then be washed and sieved to retrieve any gold – which was smelted into ingots and sent all over the empire.

Rcovery of gold in pyritic ores

Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery, and the best I have heard of is around 50% recovery. The fine coating of a iron compound definitely appears to be a key component of the inability of cyanide to efficiently leach low grade pyritic ores. Perhaps there is some room here for a pretreatment, to
