The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.
There are three stages of the dense medium separation process: feeding material pre-concentration, dense medium separation, and ferrous-based media recovery. 1. High separation efficiency and accuracy The HMS efficiency mainly depends on the specific gravity of ore particles, less affected by the size and shape of ore particles. 2.
HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of pre-concentration of minerals – mainly the production of a high weight, low assay product, which may be rejected as waste. In principle it is the simplest of all gravity processes and is a standard laboratory method for separating minerals of different specific gravity.

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 the US and Australia, dense medium separation accounted for over half of the preparation done in 2001, as shown in Table 1.8 (Cleaner Coal Technology Program, 2001). In South Africa, dense medium separation accounted for 85% of the coal preparation, due to the very high levels of near-gravity material present in coal mined in this region.
