Gravity Recovery of Gold From Within Grinding Circuits

The long residence time of the gold within the grinding circuit can cause some of the GRG to become nongravity recoverable due to smearing on to grinding media, mill liners and gangue minerals. This effect is minor as more than 98% of the GRG entering the ball mill remains gravity recoverable after grinding (LaPlante, 2000).

Small media can still grind coarse feed because of its high speed – up to 22 m/sec. The high power intensity results in a small mill with short residence times – less than a minute – which avoids overgrinding. This, together with the 8 consecutive stages of grinding and product separator, produces a sharp size distribution without external classification.
