Media losses vary considerably. In general, higher losses are associated with the finer sizes of material processed and the fineness of the media itself. Losses on the static type separators are usually low. On cyclones or DWP plants, the losses are generally higher. Table 3 shows media losses experienced in heavy media operations.

Principles of heavy media gravity separation. Heavy media gravity separation means separating products with different densities. Both magnetite and water are used to make a slurry on which one product will float (the product with a lower density than the slurry) and in which the other product will sink (the product with a higher density than the slurry).

Magnetic separation of waste is also possible for heavy materials. Researchers from the Dutch universities in Utrecht and Nijmegen have been successful: the trick is to keep the magnetic fluid containing waste stabilized when the magnetic field is more powerful. Magnetic separation of waste based on density can now be taken to a whole new level.

The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.

39.3.3 Heavy media separation. Heavy media separation dates back to several centuries. Initially, a fine magnetite was used as a heavy media. In 1936, a plant was designed employing organic liquid as a heavy media for treating anthracite coal containing ore. The heavy media process is usually used for treatment of coarse coal above 9.5 mm in

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.

In heavy media beneficiation magnetite is rinsed from ore fractions and recovered from rinse liquor by magnetic separators. The efficiency of the magnetic separation step is improved by separating the wash liquor in a hydrocyclone into a first fraction substantially free of ore contaminants and a second fraction containing most of the ore contaminants in the wash liquor.
