Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type …
Most of the reported fundamental work on the flotation of gold has been conducted using high-purity gold and gold–silver alloys with the purpose of determining collector–gold …
Preparation consists of opening up the dispersed gold inclusions in one way or another to provide access to the cyanide solution. The preparation usually consists of oxidizing …
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.
