Introduction of cyanide leaching of gold in Bulgaria
Publisher: CEE Bankwatch Network
Volume: 3 pages, pdf
Description:
In Bulgaria the cyanide leaching of gold is presently not applied. The mining sector uses cyanide for flotation processing of lead, but the concentration of cyanides in this process is significantly lower than in the cyanide leaching of gold. Since 2004 there are several investment proposals for introduction of cyanide leaching for gold extraction. These are Chelopech copper mine, Kurdjali lead and zinc processing facility, investment proposal in Krumovgrad for a new open pit mine and a cyanide leaching facility, Plovdiv lead and zinc processing facility, and at least two more at the stage of deposit exploration.
