Dry Separation Method - sssdynamics.com

Dry separation equipment first appeared over a century ago when the fluidized-bed separator, then called the specific gravity separator, was invented by Edwin Steele and Henry Sutton [1]. Constructed of wood, early gravity separators were originally developed to concentrate gold and other metallic ores without using water.

Gravity separation is used prior to flotation to separate golden particles greater than 0.1 (0.15) mm too. The lower limit size of the use of gravity separation to date is 5 microns. Major losses in golden gravity separation comprise splices of gold with other minerals, platelet-shaped particles of gold, micro and nanoparticles of gold.

Spiral Concentrator - Outotec

During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...

Gravity Separation. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest. The easiest method for achieving this is by gravity separation.
