In general, the flotation performance of these composites was very good, with high silver recoveries achieved using Potassium Amyl Xanthate (PAX) as the primary mineral collector.
The optimized rougher flotation conditions (Table-3) were: pH of pulp 8.5; grind size of ore 80% passing 100 mesh; the amount of lead nitrate as stibnite activator 300 g/ton; amyl xanthate as a stibnite collector 120 g/ton; pine oil as a frother 30 g/ton; sodium silicate as a gangue depressor 200 g/ton and sodium cyanide as a pyrite depressor 50 g/ton.

But excess [Na.sub.2]S could depress the flotation because sulfide ions hold a strong reducing capacity [22], thus the potential of mineral/water interface should be reduced, with which the generation of copper xanthate species on the sulfidized mineral surface will be affected.
