Goldbearing ores, especially the sulphidic ones, are often treated by flotation prior to cyanidation. Following flotation process, the flotation concentrate or tailings are redirected to the cyanidation circuit for gold extraction that may contain appreciable amounts of collector used in flotation, and also remained sulfide minerals,, predominantly pyrite.

GOLD FLOTATION The flotation process, which is today so extensively used for the concentration of basemetal sulphide ores and is finding increased use in many other fields. In 1932 flotation plants began to be installed for the treatment of gold and silver ores as a substitute for or in conjunction with cyanidation.
