Overview of flotation as a wastewater treatment technique
The flotation separation of very fine oil droplets (2–30 μm) is even more complicated and usually requires fine bubbles, quiescent hydrodynamic conditions in the cell separation zone or emulsion breakers prior to flotation (Gopalratnam et al., 1988). This is due to collection and adhesion factors, which makes the process very slow ...

Gold losses during flotation often occur within the fines fraction, which has been an ongoing issue that has challenged the gold mining industry. Subsequently, operations will attempt to coarsen up the primary grind to reduce the fine gold (free gold or sulphide gold) generation, resulting from over grinding. Under-grinding can then to lead to gold losses …
