Galena: The mineral galena information and pictures

Galena is by far the greatest ore of lead. The extraction process to remove the lead from the sulfur is very simple, thus lead has been extracted from Galena since the earliest times. Galena from certain regions is rich in silver, and some specimens may contain as much as 20 percent silver. Because of this, silver-rich Galena is also an ore of silver. . Another use of Galena was its importance ...

Rcovery of gold in pyritic ores - Mine Engineer.Com

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 ...
