ilmenite and silica obtained from Richards Bay in KwaZulu-Natal on the South African east coast. The ilmenite and silica were sized to between 53 μm and 500 μm (the d50 of the ilmenite was close to 150 μm and silica close to 300 μm). The ilmenite and silica were combined in ratios that were close to the average Hillendale (Exxaro KZN Sands ...
5 Gold Spiral Wheel Concentrators + Tips For Best Use
A gold spiral is a gold concentrator that uses gravity to separate gold from other materials. Spiral concentrators are one of the oldest and most famous gold recovery devices. They work by feeding gold-bearing material into a spinning wheel. The centrifugal force created by the spinning wheel separates the gold from the other materials.
