Even when times are good, there\u2019s no reason not to make every cent possible back from the precious metals waste that accumulates throughout your workshop (and which can even escape into different parts of your building). Experienced jewellers know to separate their waste by kind, by metal and by carat, but there are still some areas that we at CPM have noticed are being overlooked.<\/p>\n
Tips to capture every last speck of precious metal you can: <\/p>\n Basically \u2013 don\u2019t throw any workshop waste away that may have come into contact with precious metals dust! Collect and send in envelopes, plastic bags, papers, rags, mop heads, etc. But remember especially with low-grade refining categories like floor sweeps, make sure you accumulate a large enough volume of material to make a profit before sending in for processing.<\/p>\n Always sort your refining into types of precious metal, and especially white gold should be collected on it\u2019s own because it\u2019s palladium content necessitates a different recovery process to other forms of gold. Red and yellow gold are the only kinds that can be collected together, but they should still be isolated into the various carats \u2013 for example 18ct red and yellow may be mixed, but must be kept separate from 9ct red and yellow gold scrap.<\/p>\n CPM ACCEPTS REFINING IN THE FOLLOWING CATEGORIES:<\/strong><\/p>\n Flake and solids, comprised of: Bench sweeps and filings, comprised of: Floor sweeps and Carpets:
\n<\/strong>Grinding, filing and buffing all send clouds of microscopic precious dust into the air, which can land anywhere and be easily lost as it sticks to shoes and clothing. Make a habit of brushing or vacuuming this dust off the bench after every job (or at least every day) and especially when switching between carats or metals. If vacuuming, use a dedicated (possibly handheld) machine for the bench make sure that these filters and bags are kept separate to the ones used on the floors and other surfaces.<\/p>\n\n
<\/p>\n
\n<\/strong>Any scrap including: sprues, clean sprue grinding, stripping, clippings from claws cut to size, even engraving scraps. Basically, you should keep every bit of metal that is discarded during a job, and which is not requested back by savvy customers.<\/p>\n
\n<\/strong>High-grade filings and dust on your bench top or caught in your bench skin \u2013 supplied as clean as possible, with contaminants limited to sawblades and brush bristles.<\/p>\n
\n<\/strong>Polishings, buffs, brushes, floor sweeps, rubber wheel grindings, sanding disks and emery paper, metals lost during lapping and setting, felts, and miscellaneous workshop debris including grimy mop heads, cotton wool, wet wipes, paper towels, vacuum bags and filters.<\/p>\n
