GRAVITY CONCENTRATION OF GOLD FROM CYCLONE

Gold was subjected to the gravity concentration device in its coarsest state, i.e., as soon as a particle was discharged from the mill it saw the gravity concentration device. There were also some disadvantages: The gravity circuit had to process 3 or 4 times the new feed rate to the mill (the entire circulating load).

The Legend Of Knelson Concentrators

The patented water injection process combined with centrifugal force allowed Knelson Concentrators to recover gold that was previously considered too fine for gravity devices. The concentration cone in Byron's first ever Knelson Concentrator spun at 60 G force, and since then extensive research has proven that for 90% of gravity gold applications, 60 G's is near optimum.

Gold Gravity Concentration

Most gold ores, however, only require separation into two parts—the "concentrates," in which the precious metal is contained, and the " tailings," which are thrown away. The German system of coarse crushing, sizing by means of screens, and concentrating on jigs, is not, as a rule, applicable to gold ores proper, although much used on auriferous lead, zinc, and copper ores.

Gravity Concentration

The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises over-grinding and prevents losses due to excessive comminution, and during multiple processing
