The “mobile jig with trommel” is a combined gold and diamond processing unit that integrates a trommel screen or trommel scrubber with a jig concentrator on a single mobile platform. It first employs a rotating drum to efficiently screen and wash the raw ore, removing large waste rock and clay lumps. The qualified fine materials are then fed into a jig, where they are separated by gravity in a periodic pulsating water flow by utilizing the difference in mineral density.
Specifically, the trommel screen is suited for alluvial gold deposits with low clay content, while the laveur à tambour is designed for washing and screening ores containing high levels of sticky clay. The jig separates heavy minerals from gangue based on density. Mounted on a wheeled chassis for rapid relocation, this equipment is widely used for small- to medium-scale mobile mining operations targeting alluvial deposits such as gold and diamonds.
