Flotation of Gold and Gold-Bearing Ores - ScienceDirect
2016-1-1 · Gold hydrophobicity is enhanced by the addition of flotation collectors, and no flotation plant relies solely on the natural floatability of gold for its recovery. Naturally occurring or free (liberated) gold is optimally recovered in a flotation circuit at natural or near-natural pulp pH values and with the addition of small amounts of collector.
