The IPJ is unique in its design and use of jigging concepts. The unit is fully encapsulated and pressurized, and combines a circular bed with a moveable sieve action. The encapsulation allows the unit to be completely filled with slurry and water. As a result, slurry velocity is slowed and water surface tension eliminated resulting in higher recoveries. The screen is pulsed by a hydraulic driven shaft to achieve a saw-tooth motion, the optimum wave form for mineral separation. Separation of values from gangue particles occurs based on relative density as well as particle size and shape within the bed and are continuously discharged. The lighter mineral is discharged over the overflow to the outer cone. Both concentrates and tailings are discharged under pressure.
Low environmental footprint
- Extraction of coarse mineral or gangue prior to grinding
- Low water consumption
- Small physical footprint
- Low power requirements
Ease of operation
- Low operating cost (five cents per ton treated)
- Low installed cost (reduced capital)
- High availability
- Fully automated
- Data collection
The IPJ is designed to be able to handle a wide feed size range and recover mineral at liberation size with significant addition of water to the mass balance. A significant volume of data now supports the symbiotic benefits of the IPJ and flotation circuit combination to pre-concentrate an ore and minimise downstream processing requirements. The IPJ can be supplied as a stand-alone unit or as part of an engineered modular system and has successfully been used for a range of minerals, including gold, sulphides, silver and other heavy minerals.
