Carbon Stripping – Denver Mineral Engineers

The efficiency of the electrowinning cells is also significant to stripping efficiency. High levels of gold in recycled eluant result in a reduction in stripping rate as illustrated typically by Figure 2(3). III. PRESSURE ZADRA STRIPPING. Continued research at the USBM revealed that the Zadra process stripping rate could be
