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 ferrousbased media recovery.

LabelFree and Nondestructive Separation Technique for ...
In this study, we have demonstrated a new and simple separation technique by using wellestablished bifunctional Au–Fe 3 O 4 nanocomposites as the separation nanoprobes to efficiently isolate the specifically targeted nanomolar concentrated DNA over 70% from its associate DNA–protein mixture in the presence of a magnetic field. The sensing ...
