Of all the sulphide minerals studied so far, the depression of pyrite by free cyanide is the best understood. Free cyanide at a concentration as low as 10 mg/L NaCN was found to significantly depress pyrite flotation using sodium isopropyl xanthate (SIPX) as collector (Wet et al., 1997).The addition of 200 mg/L NaCN at pH 11 resulted in a drop in sulphur recovery from …

Flotation: Flotation is a common method used to separate silver minerals from the gangue rock. It involves adding chemicals, called collectors, to the slurry of crushed ore and water. The collectors selectively attach to the silver minerals, allowing them to be separated from the gangue rock by froth flotation.

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In general, the minerals which …
