AWA Refiners are purchasers of scrap computer boards, precious metals and high-value metals. We perform all chemical refining and melting processes at our works in Harlow, Essex. Chemical refining and melting operations are performed in house, enabling us to process all precious metals and their complex alloys. We also purchase and process Tin Alloys (including pewters, solders, joints, drosses, pastes, whitemetals and pure tin) and have a high value metal department trading in Tungsten, Cobalt, Molybdenum, Nickel, Titanium, Tantalum, Indium and their alloys. We also accept Mercury. AWA Refiners chemically refine and melt a variety of precious metals. We accept all physical grades and forms, which are then dealt with in our on site laboratory. We specialise in working with gold, silver, platinum, palladium, rhodium, iridium and ruthenium. Any materials classified as hazardous must have the appropriate paperwork, which our buying department can arrange and advise on. We are fully registered with the Environment Agency for hazardous waste (registration number AAT109).
