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.

Dense-Heavy Medium Separation HMS / DMS Process

Jun 23, 2015  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.

Dry dense medium separation of iron ore using a gas-solid ...

As a result, the iron ore with D ave ≥ 17.6 mm are successfully separated. As D ave decreases below 17.6 mm, the ore particles with density near the set point tend to scatter in the fluidized bed without floating or sinking, resulting in separation efficiency which decreases with decreasing D ave. This indicates that the size of the ore ...
