Amalgamation has been used for thousands of years to recover small sized or fine gold. Historically, it was used in many operations to increase gold recovery. In spite of this I recommend against using it in almost all applications. ... not the bright gold color associated with metallic gold. Like retort sponge, it can be melted down to pour a ...

Mercury Usage in Gold Mining and Why It Is a Problem

Gold is heavier than most other particles, so alternative methods typically use motion or water to separate the gold from lighter particles. Panning involves moving sediment that potentially contains gold in a curved pan with water and moving in such a way that any gold will settle at the bottom while the water and other particles will leave the pan.

Gold | Geoscience Australia

Free-milling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation.
