METHOD OF HOMOGENISATION AND, OPTIONALLY, ANALYSIS FOR PROCESSING MOIST NOBLE METAL-CONTAINING RECYCLING MATERIALS WITH AN UNKNOWN NOBLE METAL CONTENT

摘要

For processing of noble metal-containing, moist recycling materials with an un-known noble metal content (hereinafter called "batch"), a moisture-binding agent is added for homogenisation and the batch is mixed with comminution of optionally present 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 analysed and the noble metal content of the batch is calcu- lated on the basis of the data a previously known or pre-calculated quantity of the moisture-binding agent being added before sampling (step A).
