The Design and Operation of Heavy Medium Recovery

2009. 3. 31.  In dense medium processes for the beneficiation of minerals the consumption of medium (generally ferrosilicon) represents a major component of the operating cost. This provides a strong incentive for improvement in heavy medium recovery circuit design and operation. A major thrust in heavy medium plant design over the past decade has therefore been ...
