Abstract
Изобретение относитс к области пирометаллургического вскрыти арсенопиритных руд и концентратов и может быть использовано при извлечении мышь ка, серы и других компонентов. Целью вл етс снижение расхода соды и сокращение массопотоков. Арсенопиритный концентрат смешивают с содой, вз той в количестве 110% от стехиометрии, на вскрытие мышь ка, серы и диоксида кремни , а также остатком от выщелачивани огарка, равным по массе количеству концентрата. Смесь обжигают при 650±50°С в течение 1 ч при продувке воздуха. Огарок охлаждают и выщелчивают водой при 75±5°С в течение 2 ч. В раствор извлекаетс 97,3% мышь ка и 95,5% серы. Расход соды снижаетс на 45%, выход огарка составл ет 350-400% от стехиометрии против 530% по известному способу.The invention relates to the field of pyrometallurgical opening of arsenopyrite ores and concentrates and can be used in the extraction of arsenic, sulfur and other components. The goal is to reduce the consumption of soda and reduce the mass flow. The arsenopyrite concentrate is mixed with soda, taken in the amount of 110% of stoichiometry, for opening the mouse, sulfur and silica, as well as the residue from the leaching of cinder, equal in mass to the amount of the concentrate. The mixture is calcined at 650 ± 50 ° C for 1 h while blowing air. The calcine is cooled and leached with water at 75 ± 5 ° C for 2 hours. 97.3% of the mouse and 95.5% of sulfur are removed in the solution. Soda consumption is reduced by 45%; the yield of calcine is 350-400% of stoichiometry versus 530% by a known method.
Description
Изобретение относитс к пирометаллургии арсенопиритных руд и может быть использовано при извлечении из руд мышь ка, серы и других ценных компонентов.This invention relates to pyrometallurgy of arsenopyrite ores and can be used in the extraction of arsenic, sulfur and other valuable components from ores.
Целью изобретени вл етс снижение расхода соды и уменьшение массо-- потоков.The aim of the invention is to reduce the consumption of soda and reduce the mass flow.
Пример. 30 г арсенопиритного концентрата, содержащего, мас.%: мышь к 41,1; железо 30,8; сера 17,7; диоксид кремни 7,8, смешивают с содой в количестве 110% от стехиомет- рически необходимого дл разложени мышь ка, сульфидной серы и кремнезема , что составл ет 66 г с учетом содержани в соде 78% основного вещества , а также 30 г остатка от выщелачивани огарка. Смесь подвергают обжигу в трубчатой печи при 650+50 С в течение 1 ч при продувке воздуха со скоростью 2,3 л/мин-см2, что составл ет 150% от стехиометрически необходимого дл окислени компонентов концентрата.Example. 30 g arsenopyrite concentrate containing, wt.%: Mouse to 41.1; iron 30.8; sulfur 17.7; silicon dioxide 7.8, is mixed with soda in the amount of 110% of the stoichiometrically necessary for the decomposition of arsenic, sulfide sulfur and silica, which is 66 g, taking into account the content in the soda 78% of the basic substance, as well as 30 g of leaching residue stub The mixture is calcined in a tube furnace at 650 + 50 ° C for 1 hour while blowing air at a rate of 2.3 L / min-cm2, which is 150% of the stoichiometric concentration required for oxidation of the components.
Полученный огарок охлаждают и выщелачивают водой при Т:Ж 1:6 и температуре 75+5°С в течение 2 ч. При этом в раствор извлекаетс 97,3% мышь ка и 95,5% серы.The resulting calcine is cooled and leached with water at a T: W of 1: 6 and a temperature of 75 + 5 ° C for 2 hours. At the same time, 97.3% of the mouse and 95.5% of sulfur are removed in the solution.
Расход соды снижаетс с 200 до 110% от стехиометрии, т.е. на 45%, выход огарка снижаетс с 530 до 350- 400% от исходного концентрата, выЈь ч Soda consumption decreases from 200 to 110% of stoichiometry, i.e. by 45%, the output of the cinder is reduced from 530 to 350-400% of the original concentrate,
0505
ход остатка от концентрата составл ет 52-61% против 71%.the progress of the residue from the concentrate is 52-61% versus 71%.
Извлечение компонентов при замене части соды на остаток от выщелачивани остаетс на прежнем уровне.Extraction of the components while replacing part of the soda with the leach residue remains at the same level.
Снижение содержани соды в огарке упрощает его дальнейшую переработку и позвол ет снизить потери соды.Reducing the soda content in the candle end simplifies its further processing and reduces the loss of soda.
