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 in the coarse composite …

Froth flotation was undoubtedly the most innovative and groundbreaking discovery for mining in the 19th century (Wills and Finch, 2015).Nevertheless, it did not last long that scientists recognized its limitations for extremely fine and coarse particles, which has remained a long-standing unsolved issue in the mineral processing field (Gaudin et al., 1931).

Pre-19th century placer mining operations used mercury to dissolve the gold in crushed ore, making it easier to recover. Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules.

The aim is to remove as much as possible of the free gold contained in the circulating load of the grinding mill before it is overground or is covered with coatings of iron, sulfide, or other coatings that will lower flotation recoveries.
