What Equipment Do You Need For Alluvial Diamond Processing?

In alluvial diamond processing, the jig has become the core equipment for recovering 0.2-2mm micro-diamonds with its unique gravity sorting principle. Through precisely controlled water flow pulsation, the jig separator can increase the diamond concentration to more than 1,000 times that of the raw material within 10-30 minutes, and the recovery rate of micro-diamonds reaches 85%-92%, which is especially suitable for fine-grained alluvial deposits in South Africa, Canada and other places.

Working Principle of jig separator

The jig achieves micro-diamond sorting through the 200-400 times/minute pulsating water flow generated by the diaphragm. The high-pressure water flow (0.2-0.5MPa) first suspends the ore particles, and uses the density difference between diamonds (3.5g/cm³) and quartz sand (2.65g/cm³) to penetrate the steel ball medium bed at a speed 3 times faster during the sedimentation stage, forming a high-concentration concentrate layer. The intelligent discharge valve automatically opens and closes according to the amount of concentrate accumulated. Combined with the electromagnetic drive system’s 0.05mm amplitude accuracy, it can achieve precise capture of 0.1mm-level micro-diamonds. A single sorting can enrich diamonds by 800-1200 times.
