Dense medium separation (DMS) is one of several preconcentration methods used for early waste rejection from runofmine 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.

medium separation for lead ore. 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 ferrousbased media recovery
Chat
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, multistage dense media separators like the Condor can offer some advantages over the singlestage dense medium cyclones.

Ore sorting can run into capacity and efficiency issues if particles are below 30mm. In contrast, dense medium separators can sort particles down to 0.75mm in size. If youre working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation.
