Elution with Alcohol and NaCN - Hydrometallurgy: Leaching ...

The pressurized Zadra system has recently been the preferred process in the United States for most medium to large sized projects. This is due to its significant cost advantage over atmospheric pressure Zadra systems. The AARL process is the preferred process in Australia and South Africa, except where water balance or water quality problems exist.
