METHOD OF COPPER SULFIDE ORE FLOTATION -

The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.4, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the floation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.
