Description
Изобретение относитс к гидрометаллургии с применением низкотемпературного сульфагизирующего обжига, преимущестренно к комплексной переработке бедных окисленных оловосодер жащих руд комбинированными методами, и может быть использовано дл получени товарных концентратов олова, свинца и серебра, а также дл удалени мышь ка и других примесей. The invention relates to hydrometallurgy using low-temperature sulfagizing roasting, mainly for complex processing of lean oxidized tin-containing ores by combined methods, and can be used to produce commercial concentrates of tin, lead and silver, as well as to remove the mouse and other impurities.
Целью изобретени вл етс повышение степени извлечени свинца, снижение содержани мьшь ка в оловосодержащем концентрате, расхода серной кислоты и упрощени процесса, The aim of the invention is to increase the degree of extraction of lead, decrease the content of mice in tin-containing concentrate, the consumption of sulfuric acid and simplify the process,
Пример 1, Осуществл лась переработка некондиционного охристого оловосодержащего флотоконцентрата состава: Sn 0,98%, Pb 12,1%, Ag 320 г/т; Ре 19,8%.; As 3,4%. Example 1; Subcontracting ocherous tin-containing flotation concentrate was processed: Sn 0.98%, Pb 12.1%, Ag 320 g / t; Re 19.8% .; As 3.4%.
К этому флотоконцентрату добавл лась концентрированна серна кислота в количестве 100% по отношению к весу некондиционных флотоконцентра- тов. Полученна смесь перемешивалась и вьщерживалась 1,5 ч, образующийс твердый материал измельчалс и прокаливалс при 1 ч. После водного вьпцелачивани в раствор было извлечено 95% мышь ка и 86% железа, сереб ра и свинца менее 1%.Concentrated sulfuric acid was added to this flotation concentrate in an amount of 100% based on the weight of substandard flotation concentrates. The resulting mixture was stirred and agitated for 1.5 hours, the resulting solid material was ground and calcined at 1 hour. After aqueous aiming, 95% of the mouse and 86% of iron, silver and lead were removed to less than 1%.
После второй стадии выщелачивани насыщенным раствором хлорида натри в раствор перешло 95% свинца и 92,6% .серебра.After the second leaching stage with a saturated solution of sodium chloride, 95% of lead and 92.6% of silver were transferred to the solution.
В кремнистом кеке после вьпцелачивани концентраци олова составила 2,68% при степени извлечени 97%, содержание мьш1ь ка, свинца и железа соответственно 0,55, 2,03 и 8,75%. In the silicon cake, after concentration of tin, the concentration of tin was 2.68% with a recovery rate of 97%, the content of pulp, lead and iron, respectively, 0.55, 2.03 and 8.75%.
После осаждени свинца и серебра жженой известью были получены кеки с содержанием свинца 67% и содержанием серебра 460 г/т.After precipitating lead and silver with burnt lime, cakes were obtained with a lead content of 67% and a silver content of 460 g / t.
Пример 2. Сульфатизации по способу, описанному в примере I, подвергалс тот же некондиционный флото концентрат. Температура сульфатиза- ции составл ла . После двухста- дийного выщелачивани бьш получен оловосодержащий промпродукт. с содержанием олова 2,67%, свинца 2,53%, железа 7,4%, мышь ка 0,51%.Example 2 Sulfation by the method described in Example I was subjected to the same substandard fleet concentrate. The sulfation temperature was. After two step leaching, a tin-containing intermediate was obtained. with a tin content of 2.67%, lead 2.53%, iron 7.4%, mouse 0.51%.
После обработки солевого раствора в 2 стадии выщелачивани измельченной жженой известью был получен свинцовый концентрат с содержанием свинца 69,3% и содержанием серебра 468 г/т.After treatment of the salt solution in stage 2 of leaching with crushed burnt lime, lead concentrate was obtained with a lead content of 69.3% and a silver content of 468 g / t.
В табл.1 приведены сравнительные данные по переработке некондиционного флотоконцентрата по способу-прототипу , а также по предлагаемому при 100, 175 - 185, 250 С; при 135 - 150 С без предварительного вытеснени смеси из исходного флотоконцентрата и концентрированной серной кислоты перед сульфатизацией,Table 1 presents comparative data on the processing of off-grade flotation concentrate by the prototype method, as well as on the proposed at 100, 175 - 185, 250 C; at 135-150 ° C without prior displacement of the mixture from the initial flotation concentrate and concentrated sulfuric acid before sulfatization,
Пример 3. Сульфатизационна переработка флотоконцентрата с предварительным выдерживанием смеси этог флотоконцентрата с концентрированной серной кислотой в течение 1 ч и расходе серной кислоты, равном 1 т/т.Example 3. Sulfatization processing of a flotation concentrate with preliminary keeping a mixture of this flotation concentrate with concentrated sulfuric acid for 1 hour and a consumption of sulfuric acid equal to 1 ton / t.
Сульфатизаци по способу, описанному в примере 1, подвергалс тот же флотоконцентрат, Температура сульфа- тизатдии 135 С. После двухстадийного вьпцелачивани был получен оловосодержащий промпродукт с содержанием олова 2,,67%, свинца 1,98%, мьщгь ка 0,56%р железа 9,14%.The same flotation concentrate was subjected to sulfatisation according to the method described in example 1, Sulfatizdium temperature 135 C. After a two-stage aiming, tin-containing intermediate product with a tin content of 2 was obtained, 67%, lead 1.98%, 0.56% r iron 9.14%.
После обработки солевого раствора бьт получен свинцовый концентрат с содержанием свинца 66,3% и содержанием серебра 465 г/т, при извлечении из циркулирующих растворов на 95- 97% и из исходного некондиционного флотоконцентрата на 92 - 95%,After treatment of the salt solution, lead concentrate was obtained with a lead content of 66.3% and a silver content of 465 g / t, when extracting from circulating solutions by 95–97% and from initial substandard flotation concentrate by 92–95%,
