Investigation of effect of sulfate ion on xanthate ...

Flotation is a common process in sulfide ore beneficiation. Due to the restrictions and lack of access to high-quality water sources for industrial purposes, recycled water plays an important role in the flotation processes. Due to the existence of various organic and inorganic substances in the process, water influences the flotation performance.

The Enhancement of Galena Flotation Using Cyanide - AusIMM

The lead rougher flotation performance with and without cyanide was investigated over a wide range of redox potentials (0 mV to 400 mV SHE). In all cases, the inclusion of the cyanide brought about an increase in the galena recovery and was responsible for a faster rate of galena flotation during the initial stages of the beneficiation.

Effect of galena grain size on flotation kinetics ...

Jan 13, 2016· Laboratory tests of relationship between kinetics of flotation of pure galena smaller than 38 μm in size and concentration of potassium butyl xanthate show that flotation rate undergoes considerable reduction when mineral grains are under 18 μm in size. Size grades below 18 μm show the slowest flotation rates that are nearly equal at the collector concentration of 0.5 mg/l.

WO1993010904A1 - Flotation separation of arsenopyrite from ...

Arsenopyrite is separated from a mixture with pyrite by contacting the mixture with a sulfitic agent providing HSO3- 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 ...

Analysis of Lead Ore Ppt | Lead | Blast Furnace

Flotation The principal lead ore, galena, is properly known as lead sulfide, and sulfur makes up a substantial portion of the mineral. The flotation process collects the sulfur-bearing portions of the ore, which also contains the valuable metal. First, the finely crushed ore is diluted with water and then poured into a tank called a flotation cell.
