Less selective mining affects the feed to the jig plant, as is also the case with feeding the DMS plant. Because of the size of the open pit (12 km χ 2.5 km), the feed to the plant is trucked from different loading points in the mine with ore types that differ mineralogically, resulting in variation in the chemical composition of the feed.

Sishen is one of the largest open pit mines in the world – some 14km long. The jig plant at Sishen mine is the largest of its type in the world. Sishen operation includes: 13 active open pits, 24 waste rock dumps including stockpiles, 4 tailings’ facilities, beneficiation plant and other infrastructure. Kumba plans to extend life-of-mine to 2044.

Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 μm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.

2014年7月1日 · During commissioning and ramp-up the shortcomings and advantages of the jigs were fully experienced and understood, resulting in many changes to optimize jigging performance. Sishen Iron Ore Mine previously used only A-grade material (>60% Fe in situ value) from the pit for beneficiating in the DMS plant to a final product grade of 66% Fe in ...

2014年7月1日 · The ability to beneficiate the B-grade material at densities higher than 3600 kg/m(3) was evaluated, and air-pulsed jigs were found to be techno-economically feasible and value maximizing.

massive type hematite ore of which 30 Mt is being beneficiated by Dense Medium Separation (DMS), while the remaining 10 Mt is processed by the jig plant that was added as an expansion to the DMS processing route. The jigs at the jig plant are employed to treat coarse, medium and fine Run of Mine Ore (ROM).

The jigs at Sishen Iron Ore Mine are under-bed pulsating jigs that are fully PLC-controlled. All the jigs are 3 m long, and the width varies from 4 m for the Coarse Jig to 3.5 m for the Medium and 2.2 m for the Fine Jig. The different widths for the jigs were selected to …

At SPARKS MET (PTY) LTD, we design, manufacture and refurbish various Mineral Jigs to make sure the effective recovery and optimal yields or ore. CALL US our strategy:

The ability to beneficiate the B-grade material at densities higher than 3600 kg/m 3 was evaluated, and air-pulsed jigs were found to be techno-economically feasible and value maximizing. The beneficiation of B-grade material would add to the existing DMS production of 28 Mt/a, with no additional mining cost and only limited costs for the ...

The Sishen Jig Plant is the largest facility of its kind in the world. A joint venture development agreement was signed between Kumba and Exxaro in April 2012 to utilise the latter’s ultra-high dense-medium separation (UHDMS) technology in Kumba operation.
