RECENT DEVELOPMENTS IN PRECONCENTRATION USING

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 Medium Separation - An Effective and Robust Pre ...

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.

Ore Sorting vs. Dense Medium Separation In Mineral Processing

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 you’re working with finer particles, dense medium separation is the way to go. Higher tonnages can also be accommodated with dense medium separation.

Mineral processing - Wikipedia

In dense media separation a media is created with a density in between the density of the ore and gangue particles. When subjected to this media particles either float or sink depending on their density relative to the media. In this way the separation takes place purely on density differences and does not, in principle, relay on any other ...
