Dense Medium Separation An Effective and Robust Pre

2018-2-20  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.

Partition Curve an overview ScienceDirect Topics

The partition curve for an operating dense medium vessel can be determined by sampling the sink and float products and performing heavy liquid tests to determine the amount of material in each density fraction. The range of liquid densities applied must envelope the working density of the dense medium unit. The results of heavy liquid tests on samples of floats and sinks from a
