MoreAug 17, 2021 Redox regents were efficient in removing copper and silver that enabled our client to refine 95-99% pure gold from the starting material. The reagents used were of such high quality that they enabled a great quality flux, in much the same way as making a great cake starts with quality ingredients – so should gold be refined from high-quality fresh ingredients to produce a better product.
Morecopper refining. We do copper concentrate undergoes refining via one of a few processes. The least common method is cementation, in which an acidic solution of copper is deposited onto scrap iron in an oxidation-reduction reaction. After enough copper has been plated, the copper is then further refined.
MoreThis oxidation-reduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of 99.5 percent copper that is required for electrolytic refining. At this point, the copper is cast into anodes, the shape and weight of which are dictated by the particular electrolytic refinery. Leaching
