Pyrite Tailings Recovery by Flotation

Pyrite has long been used as a source of sulphur, and its recovery as a by-product from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite. In many instances these tailings can be treated to yield pyrite .

Metallurgical process - DRDGOLD

Traditional recovery. Tailings retreatment in South Africa began in the 1970s incorporating a technique known as flotation to recover pyrite uranium and gold. A CIL circuit was later added to enhance gold production. Three decades had passed before DRDGOLD acquired the Brakpan plant in 2007 with the aim of re-establishing the Ergo project.

Pyrite Mineral | Uses and Properties

If pyrite contains 0.25% gold and the gold price is 1500 per troy ounce, then one ton of pyrite will contain about 73 troy ounces of gold worth over 109,000. That is not a guaranteed money-maker. It depends upon how efficiently the gold can be recovered and the cost of the recovery process.

Project | New Carolin Gold Corp.

The combination of flotation yields 91.3% gold recovery and cyanidation of the flotation tailings yields 75.7% gold recovery. In combination, flotation plus cyanidation of the float tail yielded (91.3 + 75.7 x (100-91.3)/100 = 97.9% recovery. The recovery of gold by pressure oxidation and CIL of the autoclave residue is currently being tested.
