Description
Изобретение относитс к области металлургии цветных металлов.This invention relates to the field of non-ferrous metallurgy.
Известен способ переработки золотомышь ковоуглистых концентратов , включающий окислительный обжиг, цианирование, осаждение золота из раствора на активированном угле, обжиг и плавку осадка .на золото.There is a method of processing gold-copper kovoglisty concentrates, including oxidative roasting, cyanidation, precipitation of gold from a solution on activated carbon, roasting and smelting of sediment on gold.
По предложенному способу исходное сырье подвергают вакуумированию при 600-1100 С с остаточным давлет нием до 20 Торр вакуум-остаток обрабатывают сол ной кислотой при температуре до 110°с 1-4 ч и золотосодержащий кек подвергают обжигу, после которого из огарков извлекают золото и другие благородные металлы. Это увеличивает комплексность использовани сырь и повыщает извлечение золота.According to the proposed method, the feedstock is evacuated at 600-1100 ° C with a residual pressure of up to 20 Torr. The vacuum residue is treated with hydrochloric acid at a temperature of up to 110 ° C for 1-4 hours and the gold-containing cake is fired, after which gold and other noble metals. This increases the complexity of the use of raw materials and increases the extraction of gold.
Сущность предложенного способа заключаетс в следующем.The essence of the proposed method is as follows.
Концентрат подвергают вакуумнотермической обработке при 600-1100 С (в зависимости от спекаемости концентрата ) и остаточном давлении ниж.е 20 Торр в течение не менее 15 мин дл выделени мышь ка в возгоны. Затем вакуум-остаток обрабатывают сол ной кислотой при температуреThe concentrate is subjected to vacuum thermal treatment at 600-1100 ° C (depending on the sintering ability of the concentrate) and a residual pressure of less than 20 Torr for at least 15 minutes to release the mouse into sublimates. Then the vacuum residue is treated with hydrochloric acid at a temperature of
цо 110°С в течение 1-4 ч. При этом происходит практически полное извлечение железа в раствор, из которого при последующей регенерации кислоты гидрот)мическим методом железо выдел етс в виде чистой окиси железа и может быть использовано как сырье дл доменного процесса. Кроме того, в раствор при этом 110 ° C for 1–4 h. At the same time, iron is almost completely removed into the solution, from which, during subsequent acid regeneration by the hydrotromatic method, iron is released as pure iron oxide and can be used as a raw material for the blast furnace process. In addition, the solution while
0 извлекшот свинец и цинк, из которого их выдел ют в виде сульфидов и направл ют на свинцово-цинковое производство . Кек от выщелачивани (золотосодержащий продукт) подвергают окис5 литедьному обжигу при температуре до 1100°С дл удалени углистых веществ, мешающих извлечению золота цианированием . Затем провод т цианирование огарков, с Последующим выделе0 нием золота известными методами.Lead and zinc are extracted, from which they are separated as sulphides and sent to lead-zinc production. The leaching cake (gold product) is subjected to oxide firing at temperatures up to 1100 ° C to remove carbonaceous substances that prevent the extraction of gold by cyanidation. Then, cyanidation of stubs is performed, followed by gold extraction by known methods.
