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 at least one representative, volume-reduced sample is taken first of all, B the sample is dried, C the sample is optionally divided further and D the sample is analyzed and the noble metal content of the batch is calculated on the basis of the data a previously known or pre-calculated quantity of the moisture-binding agent being added before sampling (step A).
