Refractory ores are typically treated by flotation and the resulting flotation concentrate may be sold directly to a smelter (common, for example, in China) or subjected to downstream processing by pressure oxidation or bio-leach. An ore containing 1% S will produce a mass pull of approximately 3% by weight to a flotation concentrate.
