gold and copper flotation

In flotation of goldcontaining base metal ores a number of modifiers normally used for selective flotation of copper lead lead zinc and copper lead zinc have a negative effect on the floatability of gold Such modifiers include ZnSO 4 7H 2 O SO 2Na 2 S 2 O 5 and cyanide when added in excessive amounts
