 Whether at a jeweler, a goldsmith or in a dental laboratory: wherever gold, silver and platinum are worked with, waste is generated. Despite their size, this waste in the form of shavings, leftover pieces, sawdust or dust is valuable if it is collected and recycled.
 For decades, CM Hoke's book "Refining Precious Metal Wastes" was THE book that contained the "secret" knowledge of an entire industry. Published in 1940, it has provided thousands of jewelers, goldsmiths and metalworkers with precisely the valuable information they could use profitably in their daily work.
 CM Hoke has taken a completely different, extremely modern approach: making the knowledge accessible to everyone - even non-experts. The book therefore does not contain a single chemical reaction equation, no complicated calculations and does not require any prior knowledge. It is written in a generally understandable, sometimes even entertaining language. Nevertheless, everything you need to know for this work is explained precisely and comprehensibly. This is the first German translation of a book that is still a worldwide bestseller in its original English version. Learn here how to recover gold, silver, palladium and platinum from waste from goldsmiths, dental laboratories, etc.!
 The loving, careful translation by the author MA Buth has been linguistically and technically checked and extensively revised. This translation therefore offers more current references and information than the original text can. Illustrations from the original have been taken and supplemented with current images where necessary. An extensive bibliography shows the way to even more information on the subject of precious metals and their recycling.
