Abstract
Способ переработки концентратов, содержащих благородные металлы и сульфиды, включающий термическую обработку исходного материала и последующую плавку продукта термообработки в смеси с карбонатом натрия, кремнеземсодержащим флюсом и углеродистым восстановителем с получением сплава благородных металлов и шлака, отличающийся тем, что исходный концентрат смешивают с нитратом и карбонатом натрия в соотношении 1:(0,5÷1,6):(0,1÷0,4), смесь выдерживают при температуре 400÷600°C, полученный спек выщелачивают в воде с последующим отделением нерастворимого осадка от раствора, нерастворимый осадок сушат и плавят с добавками буры и оксида кальция. A method of processing concentrates containing noble metals and sulfides, including heat treatment of the starting material and subsequent melting of the heat-treated product in a mixture with sodium carbonate, silica-containing flux and a carbon reducing agent to produce an alloy of noble metals and slag, characterized in that the starting concentrate is mixed with nitrate and carbonate sodium in a ratio of 1: (0.5 ÷ 1.6) :( 0.1 ÷ 0.4), the mixture is maintained at a temperature of 400 ÷ 600 ° C, the obtained cake is leached in water, followed by separation of insoluble th precipitate from the solution, the insoluble precipitate is dried and melted with addition of borax and calcium oxide.
