dense media separation for iron ore

Major Mines & Projects | Kolomela Mine

The mine commissioned a small-scale modular dense media separation (DMS) plant in 2016 to treat lower Fe-grade ore; scheduled throughput through this DMS plant has been increased in the 2017 LoM plan, resulting in a lowering of the overall average yield.

Dense Media Separation

Dense media separators are commonly used for preconcentration of coal and diamonds but less commonly for other mineral systems such as lead and zinc. Due to lower head grades adding to the complexities of the ore, multi-stage dense media separators like the Condor can offer some advantages over the single-stage dense medium cyclones.

Dense media separation

Dense medium separation (DMS) is one of several preconcentration methods used for early waste rejection from run-of-mine ores at relatively coarse particle sizes prior to additional milling and beneficiation. DMS has been used extensively in the coal, diamonds, mineral sands, base metals and iron ore industries to produce either a final product or as a preconcentration step.
