Abstract:
A perfectible bulk flotation simplified technology was developed to produce initially a collective polymetallic concentrate for further treatment by a “sulphatization roasting → 2-step leaching metal cementation” method to recover all valuable metals besides the noble metals, and after this, recover gold and silver from the base metal leaching residuum by cyanide leaching and following electrowinning. It has been showed that all gold bearing sulphides copper, zinc, lead and iron were successfully passed from polymetallic ore into collective concentrate which is a pleasurable perspective for complex and effective recovery of all valuable metals contained.
