Sawtooth wave jig is revised and manufactured, based on the stratified theory and the adequate analysis of other conventional jigs. The jigging pulsation curve----produced by sawtooth wave jig----is in the shape of sawtooth wave which makes upward water flow quicker than downward water flow.
Free-Milling Gold. Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm. Some examples of free-milling gold ores include quartz-veined deposits and oxidized ores. Sulfide-Associated Gold
Recovery depends upon mineralisation type and comminution and extraction method used. For example, centrifugal concentrators may recover gold down to 20 µm in size, whereas jigs are more likely to be restricted to >100 µm. Any ore type bearing >25% of gold greater than 50 µm to 100 µm in size is likely to have a high GRG component.
