The optimum recovery of gold was obtained by adding (NH 4) 2 S 2 O 3, oil emulsions and sulfur into the mill, together with butyl xanthate as the collector in weak acidic pulp adjusted by H 2 SO 4. Fundamental concepts of gold flotation were considered, including the sulfur-oil-gold agglomeration mechanisms and the role of (NH 4) 2 S 2 O 3.
