Particle sorting of ore has been used since the times of artisanal miners, hand selecting the best rocks for smelting to optimise product quality and volume (Agricola, 1556). In modern times, mines have found ways to automate this process using physical properties such as density (eg dense media separation).

Gold Processing,Extraction,Smelting Plant Design ...

Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.

3. Gravity separation process used in gold separation. Because of the large proportion of gold, gravity separation process is the most common method of recovering gold, and is often used in combination with other gold separation methods to treat all kinds of gold ores, especially the alluvial gold mine.

Electrostatic Separation | Electrostatic Separator ...

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
