Gravity separation has long been a favoured method of recovering gold.
Gold pan is the most primitive and simple gravity beneficiation equipment. You scoop placer gold ores in the pan, and agitate gently in water until the gold sinks to the bottom of the pan. But it has a small processing capacity and a slow sorting speed. In order to recover gold in large quantities and quickly, people have invented several gravity gravity separation equipment[b] https://www.ftmmachinery.com/blog/gold-gravity-separation-equipment.html[/b].

Shaking table
Gold shaker tables are good at sorting[b] fine-grained minerals[/b]. Shaking tables have different effective recovery particle sizes to adapt to ores with different particle sizes. Shaker tables with a maximum feed particle size of 2mm are for coarse ores, 0.5mm for fine ores, 0.15 for slime.
Gold shaker tables are often used for concentration.

Spiral chute
The spiral separator is suitable for processing alluvial gold ore, especially for gold ore with a high degree of monomer dissociation and flat shape. Besides, it is also good at dealing with fine gold ore with particle sizes between 0.003-0.6mm containing low mud content.
Spiral chutes are often used for rough concentration.

Gold jig
Mineral jig concentrators are good at separating coarse-grained minerals. When processing placer gold ores with high monomer dissociation degree and large difference in specific gravity of gangue minerals, it can achieve a better separation effect.
Jig machines are often used for concentration and rough concentration.

The above three commonly used gold gravity separation equipment have their own pros and cons. In the gold processing plants, gold miners often use them in combination. For example, first use a jig to obtain rough gold concentrate, then use a shaking table to further concentrate it.
