As high-grade mineral deposits continue to decline and lower-grade ores become increasingly common, pre-concentration has become an essential strategy for improving processing efficiency and reducing operating costs. By utilizing advanced gravity separation technologies, Sormak upgrades lead, zinc, and other mineral ores before they enter the grinding and flotation circuits, thereby increasing plant performance and overall recovery.

The unit is equipped with a range of gravity separation systems, including Heavy Media Separation (HMS), Dynawhirlpool separators, Dense Medium Cyclones (DMC), spiral concentrators, and shaking tables. These technologies separate minerals based on differences in specific gravity, producing three distinct streams: concentrate, middlings, and tailings.

The implementation of pre-concentration significantly reduces the load on downstream grinding circuits, resulting in lower energy consumption, reduced equipment wear, decreased processing costs, and improved overall plant efficiency. Furthermore, because these gravity-based processes operate without the use of chemical reagents, they provide an environmentally friendly and cost-effective solution for mineral beneficiation.
