    The flotation alone produced a concentrate too low in gold content (less than 100 g/t) to be accepted by smelters, which prefer to process high grade gold cyanidation precipitates. Cyanidation of the flotation concentrate (10% by weight) rather than that of the entire ore plant feed is likely to present a significant economic advantage, despite

    If the gold is combined with the copper than if your current grade is 0.8 g/t (grade), to raise this you need to reduce the overall recovery, and lose copper. If the gold is separate than you need to adjust the scavenger and re cleaner circuits to get more recovery of the gold by adjusting the reagents.
