Heavy medium cyclone; simulation; lead and zinc; pre-concentration Introduction Dense-media separation (DMS) (or) heavy-media separation (HMS) or sink-float separation is one of the most important and fundamental gravity separation methods. In fact, this process has been used over 100 years since 1900.[1]
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.
Dense Media Separators Dense media separators can be categorized into two groups (Wills & Napier, 2006): gravitational (static) and centrifugal (dynamic). In gravitational units, the feed and medium are introduced into the vessel and the mixture is gently agitated to maintain a fluidized bed. The less dense minerals are removed

Product Overview. Condor Dense Medium Separators provide a simple, cost-effective way to separate and recover valuable minerals at a coarse particle size, ranging from as fine as 0.5 mm to as coarse as 50-70 mm but typically in the range of 1- 50 mm. Dense medium separation technology is used for a wide range of mineral separations to produce premium concentrate.
Typically, different grades of ore are blended according to required specifications and then crushed, followed by screening into fines and lump ore. The ore may then undergo dense media separation after which, silicon waste is removed typically through flotation separation, and clays and other contaminants are washed out.
