Mar 01, 2021If the concentrate has a high grade of gold, for instance 30,000 g Au/tonne (or 3% Au) or above, the yellow concentrate can be directly smelted (Appel and Na-Oy, 2011). If the concentrate does not have a high grade, the particles of gold will not coalesce during the smelting process to create enough weight to sink in the molten bath.

The InLine Leach Reactor

The jigs produced 54 kg/hr of sulphide rich concentrate containing 800 g/t gold from an average mill feed of 2.4 g/t. This represented a recovery of approximately 13.5% of the gold fed to the mill. The ILR100 recovered 94.5% of the gold in this concentrate. Dissolved oxygen was maintained between 20 and 30 ppm by the electrowinning cell.
