The hydrometallurgical routes rely on wet chemistry ,extraction, and precipitation techniques. For example the catalysts undergo a pre-treatment stage to dissolve the catalytic support and the then the noble metals can be leached using a suitable lixiviant such as aqua regia or sulphuric ,acid, depending on the selectivity required or chemistry of the metals.
