Navachab Gold Mine boosts recovery with STEINERT’s technology Navachab Gold Mine, a low-grade gold ore operation, upgrades its low-grade ore resources using STEINERT’s suite of innovative dry sorting processes. At Navachab it has been possible to double the gold grade. As the STEINERT machines require a minimum of water the technology is environmentally friendly. The low operating costs and modularity make the machine very easy to integrate into existing circuits.
N avachab has been using STEINERT XSS T sorters since 2016. Over the last decade, these sorters have preconcentrated over 10 million tons of low-grade stockpiles and turned it into valuable ore, which were previously considered uneconomical to process. Navachab Gold Mine has now installed the next generation of STEINERT’s sorting systems: STEINERT KSS EVO 6.0. Hildebrand Wilhelm states: “The more of a holistic view you have, the better you can decide what technologies can work, as long as you understand these technologies.” The next evolution being considered is a doubling of current treatment capability. Compared to previous processes using Dense Media Separation (DMS), dry, sensor- based sorting now runs at 1/4 of the overall operational costs, while doubling throughput. For these reasons, and because this process does not require water, it plays a key role in the future. From single sensor to multi-sensor sorting The metallurgist is amazed by the detection rate per second – and the fact that the dry sorting plant sorts 200 tons continents rely on Kal Tire for mining tire management expertise, independent supply and innovation at every stage of tire life. To support customers on their sustainability journey, we’ve established proven repair and retread solutions, a Maple Program providing validated emissions savings data, and thermal conversion recycling technology that transforms end-of-life OTR tires into valuable commodities. To make our work as safe and productive as possible while enhancing tire performance, we design proprietary service tools at our Innovation Centre— and our offerings include TOMS (Tire &
per hour to detect material falling below the CIP plant cut-off grade. “That is where the value is generated because then – with the doubled grade – the material can be profitably treated by the downstream processes,” he emphasises. The former sorting systems were robust, reliable and withstood 10 years of harsh and dusty mining conditions. Sensor-based sorting combined with Intelligent.Declustering for more throughput STEINERT has a new solution in the field of data interpretation. Particle sorting technology typically analyses and makes
decisions regarding individual defined particles on the conveyor belt. With STEINERT’s Intelligent.Declustering, the software extracts the individual rock from the cluster, even if the particles are close together, and analyses it. n
