Depression of pyrite in the flotation of high pyrite low

In this research work, selective depression of pyrite in the flotation of a low-grade lead-zinc ore containing 31% pyrite was investigated in the absence and presence of Acidithiobacillus ferrooxidans. Pyrite was significantly depressed with these bacteria using the optimum dosage of reagents. Sphalerite recovery and Zn grade in the obtained sphalerite concentrate were both enhanced by

Evaluation of the replacement of NaCN with

2011-7-29  We investigated the replacement of NaCN with Acidithiobacillus ferrooxidans, in the flotation of a low-grade lead–zinc ore containing high amounts of pyrite.A. ferrooxidans were adapted to original ore, and its growth curves were monitored before and after adaptation. Because of its characteristics, the addition of original ore caused the bacterial cell count to increase in the culture

THE INFLUENCE OF CYANIDE SALTS AND FERROUS

2016-5-17  whereas the commonest reagents for its depression in lead-zinc ore flotation are of cyanide type. However, cyanides are not mainly in use for pyrite depression in copper ore flotation. Depressing effect is achieved with OH– ions at high pH, mostly with lime. The first published data about the depressing effect of cyanide were found in 1922.
