High recovery jigs

Maximising the recovery of valuable minerals through gravity separation in alluvial mining, hard rock pre-concentration, and recycling industry.

High recovery jigs in short

Our high recovery jigs are used in wet gravity concentrations, where particles with different particle densities are separated, and can be concentrated. The high recovery jig is a thick bed separator, separating particles purely on density and not on shape or size.

It's modular design, trapezoidal-shaped bed and saw-tooth drive result in an optimal recovery and high upgrade of the valuable heavy mineral. Even for the finest particles (down to 50 µm) and at low density differences.

Originally developed for alluvial mining applications, the technology continues to prove its relevance today in both primary and secondary resource recovery across mining and recycling industries.

From single modules to integrated gravity concentration plants

The jig is modular by design. The trapezoidal shape of the jig allows for a circular arrangement, thus increasing capacity while keeping the footprint to a minimum. Based on the required feed capacity, the choice of jig cells can be up to 12 modules.

Royal IHC’s high recovery jigs were originally developed for application in typical alluvial or placer deposits containing valuable minerals like gold, tin, diamonds and tungsten. But they are also perfectly suited to recover valuable metals from incinerator bottom ash.

We offer a versatile range of high-recovery jig installations, from single modules to integrated three-stage gravity concentration plants, tailored to individual requirements.

Drive systems

The heart of the jig is the asymmetrical drive system, which delivers the gravitational movement that separates heavy and light particles in the jig bed. The saw-tooth stroke pattern was developed and introduced to the market by IHC Mining and enables a high-unit capacity and optimal recovery. The system can be both mechanical and mechanical-hydraulic.
