Abstract

For processing of noble metal-containing, moist recycling materials with an unknown noble metal content (hereinafter called “batch”), a moisture-binding agent is added for homogenisation and the batch is mixed with comminution of optionally pre-sent agglomerates to form a free-flowing and homogenous powder. Optionally, the following takes place subsequently for analysis: a previously known or pre-calculated quantity of the moisture-binding agent being added before sampling (step A).
