However, Chapman model was selected as the best one for the flotation of pyrite and molybdenite. In case of the common first order flotation kinetics models, fast and slow flotation kinetic model (Kelsall) was reasonably fitted the best to the given data of chalcopyrite.
chalcopyrite flotation gold icas2017conference
Gold; Flotation I. INTRODUCTION Froth flotation is a widely used separating technique for the recovery of Cu and Au in porphyry coppergold ores. In these ores, chalcopyrite and gold are the main valuable mineral/metal phases, with pyrite being the key sulphide gangue mineral. However, in these ores gold is mostly associated with pyrite.

Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery
Gold Pyrite, Pyrrhotite and Arsenopyrite Recovery. Copper sulfate is often used as an activator in the flotation of gold associated with iron sulfides. Experimentally, when copper sulfate is used in the flotation of gold bearing pyritic ores, the recovery is higher and the rate of flotation is faster.

US5171428A Flotation separation of arsenopyrite from
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

Monometallic Flotation Process Plant Copper Base Metals. This complete process plant is for recovering metal monometallic ore deposits. This applies, but is not limited to, the recovery by froth flotation of most base metals Copper, Lead, Zinc, Cobalt, Nickel, Molybdenum, Pyrite, Pyrite Gold, Silver Sulphides.This process will also recover silver and/or gold associated with sulphide minerals.

The Leachox Refractory Gold Process maelgwyn
The Leachox refractory gold process has to date been applied to the selectivetreatment of several refractory gold ores but on a relatively small scale. In this paper the successful implementation of the process, from initial testing through to commissioning at one of the worlds largest refractory gold
Optimisation of gold recovery by selective gold flotation
Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated away from an ore containing sulphides.
Gold Flotation Mineral Processing Metallurgy
Promoters or Collectors. The commonly used promoters or collectors are Aerofloat reagents and the xanthates. The most effective promoter of free gold is Aerofloat flotation reagent 208. When auriferous pyrite is present, this reagent and reagent 301 constitute the most effective promoter combination.
