Separation Density - an overview ScienceDirect Topics

10.2 Dense medium separation10.2.1 Principle. DMS is a gravity separation process. In the strictest sense, it implies separation of lower-density particles from higher-density particles at a specific separating density regardless of size, shape, and other secondary influences. In industrial reality, such simplistic gravity separation is seldom ...
