Froth flotation is considered an effective separation method for sulfide ores and has been applied at the industrial scale for many years [1], [2]. Milling is a key procedure with a significant impact on the subsequent flotation process toward the achievement of a suitable particle size distribution [3], [4], [5].

The gold grade is low, the natural gold grain is relatively small, and is mostly wrapped in pyrite. It is generally easier to separate gold from sulfide by froth flotation process. But the separation between gold and sulfide needs the complex combined process, otherwise the gold ore processing indexes won't be too high. 3. Read More

For example, in order to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant. It selectively allows PbS form froth, but prevents ZnS from coming to froth. This happens due to the fact that NaCN reacts with ZnS to form Na 2 [Zn(CN) 4]. What is the frothing agent in froth floatation process?

How does gold flotation work? Froth flotation works by exploiting the hydrophobic properties of gold molecules. Aided by the surfactant, the water repels the gold into the air bubbles, which rise to the top – creating a bubbly golden froth. The froth is skimmed from the surface and collected and later condensed into metallic gold.
