Electrostatic Separation an overview | ScienceDirect Topics
The dry stream of moving particles is preferred between 75 and 250 μm, An NIR camera or an alternative sensor system analyzes the particles coming across and controls a blowing device that may then blow a particle out of a waste stream, if the sensor results indicate the presence (or absence) of a given polymer. These sorting techniques are rather effective; however, they work best with

HMS and DMS are acronyms for Heavy (Dense) Medium Separation and is applied to the process of preconcentration 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. Fluids of suitable density

01/04/2014· The original gold winnowing process was a dry separation technique, accomplished by wrapping sandy gold ore in a woolen blanket, which was then shaken up and down by two men (Wilson, 1961). In the process, the gold particles were triboelectrically charged and attached to the blanket. Then, the blanket was opened, and the material was tossed into the air, causing the sand particles to blow

Once you have removed nearly everything but the gold, use your magnet and stir the material at the bottom of the pan to pick out the remaining fine textured sands. Once finished with this wet separation process, you should be down to almost clean gold. Dry whatever you have left and inspect it carefully. There will likely still be a few particles of mineral other than gold, but they should be reduced
