Abstract
Способ определения благородных металлов в рудах и продуктах их переработки, включающий смешивание навески пробы анализируемого материала с флюсами, оксидом свинца, нитратом или хлоридом серебра и углеродистым восстановителем с получением смеси, плавку смеси при температуре 1100-1300°С с получением шлака и свинцового сплава - веркблея, охлаждение и разделение продуктов плавки, купелирование веркблея до серебряного королька и определение содержания благородных металлов в серебряном корольке химическими и физико-химическими методами, отличающийся тем, что перед купелированием к веркблею добавляют металлическое олово в количестве 0,4-1,0% от массы веркблея и купелирование ведут при температуре 880-930°С. The method for determining precious metals in ores and products of their processing, including mixing a sample of the analyzed material with fluxes, lead oxide, nitrate or silver chloride and a carbon reducing agent to produce a mixture, melting the mixture at a temperature of 1100-1300 ° C to obtain slag and lead alloy Verkbley, cooling and separation of smelting products, cupellation of Verkbley to a silver bead and determination of the content of noble metals in a silver bead by chemical and physico-chemical methods, cast ayuschiysya in that before cupellation lead bullion is added to metallic tin in an amount of 0.4-1.0% by weight of the crude lead and cupellation carried out at a temperature of 880-930 ° C.
