Problems with free gold flotation in a low sulfide ore include the high density of the free gold and the low concentration of the gold in the ore—the low concentrations make for an unstable froth. However, flotation of gold-bearing sulfides such as pyrite or arsenopyrite are done very commonly and can be an alternative.
