Subject category Comment text
Deposit BENIFICIATION IS BY TWO CIRCUITS - GRAVITY AND FLOTATION. THE MILL IS SUPPLIED EQUALLY BY OPEN PIT OPERATIONS(GRAVITY) AND UNDERGROUND OPERATIONS (FLOTATION). THE CONCENTRATES ARE COMBINED BEFORE CYANIDATION AND ZINC DUST PRECIPITATION. THE BULLION IS REFINED AT A NEARBY REFINERY AND THE FINE GOLD AND SILVER ARE SOLD ON THE OPEN MARKET.
