2016-3-1 The AARL process consists of three steps: a hot acid wash followed by a hot caustic cyanide pre-treatment and afterwards elution with hot deionized water at high pressures (up to 300 kPa). According to the researchers, test results show that effective elution of platinum- and palladium-cyanide with the AARL method is feasible. Related Content.
