    Jun 15, 20190183;32;Nickel ores that have a high pyrite content can be floated by reverse flotation in which pyrite reports to the concentrate and pentlandite to the tailings stream. This is because nickel is easily depressed at a pH above 9.5, enabling the pyrite to be selectively floated under alkaline conditions.
