The efficiency of physical separation techniques of heavy minerals usually encounters some set-backs. The reason is often not far from the inability to develop suitable mineral characterization strategies in order to comprehend/evaluate certain physicochemical features such as surface chemistry, specific gravity difference, magnetic and electrical …
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 ...
