Natural pH is recommended for gold flotation. Alternatively using soda ash for pH adjustment can reduce gold depression. Where gold is associated with pyrite in base metal ores where iron sulphides are depressed and report to the tailings, a separate tailings pyrite flotation concentrate should be considered.

Pyrite Tailings Recovery by Flotation

Pyrite has long been used as a source of sulphur, and its recovery as a byproduct 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 concentrates that are a

Depressants for Pyrite / Flotation depressants

Flotation results indicate that PIONERA BioPolymers, at each dosage, significantly reduce pyrite than conventional pyrite depressants. Additionally, conventional pyrite depressants such as sodium cyanide, sodium hydro sulfide and Nokes reagent are toxic, highly regulated, difficult to handle and present an overall costly alternative.

Application of Flotation . Whether the gold ore is applicable to the flotation method depends on whether it has better floatability. For simple ore just containing gold, and the granularity of gold is uniform, and high floatability, simple grinding and flotation process is always the best solution.

Pyrite

Pyrite

The mineral pyrite (/ p a r a t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common form of sulfide minerals. Pyrite's metallic luster and pale brassyellow hue give it a superficial resemblance to gold, hence the wellknown nickname

Sodium silicate was somewhat effective in causing a differential or selective flotation of copper, as chalcopyrite from pyrite by keeping pyrite from floating. Sodium hydroxide and sodium sulfide gave, in most cases, a distinct separation of sphalerite from chalcopyrite; i.e., a high copper and low zinc by suppressing the flotation of sphalerite.

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO 3 ions at elevated temperature and pH below about 8 for a period sufficient to impart a selective depression property to the arsenopyrite. On addition of a collector the pyrite is rendered floatable, enabling froth flotation to achieve a concentrate rich in pyrite and tailings
