Description

В насто щее врем  сульфидные руды при получении из них меди, цинка и свйнца подвергаютс  флотационному обогащению, при этом в флотационных хвостах и пирнтных концентратах тер етс  много меди, золота, серебра и свинца.At present, sulphide ores, when copper, zinc and sugar are produced from them, undergo flotation enrichment, while a great deal of copper, gold, silver and lead is lost in flotation tailings and ground concentrates.

В основном авт. св. № 44231 описей способ получени  серы из колчеданов с нрименение.м концентрированного кислорода дл  обжига колчедана во взвещенном состо нии с одновременным использованием цветных ,и благородных металлов, содержащихс  в сырье.Basically auth. St. No. 44231 descriptions of the method for producing sulfur from pyrites with the use of concentrated oxygen for calcining pyrites in the exploded state with simultaneous use of non-ferrous and noble metals contained in the raw material.

Предлагаемый способ отличаетс  от известных тем, что п юизвод т зональный обжиг пылевидного сульфидного сырь  совместно с флюсами (кварцем и известн ком) во взвещенном состо нии, при определенном количестве воздуха и в присутствии вод ного пара, причем дутье не разбавл ют инертными газами и вод цой пар подают выше фокуса горени . Содержащийс  в сульфидном сырье цинк улавливают в виде окиси в электрофильтре.The proposed method differs from the known ones in that the zonal calcination of pulverized sulphide raw material together with fluxes (quartz and limestone) in a forced state, with a certain amount of air and in the presence of water vapor is produced, and the blast is not diluted with inert gases and water. The steam is fed above the focal point of combustion. The zinc contained in the sulphide raw material is trapped as oxide in an electrostatic precipitator.

Выход щие газы, состо щие после конденсации серы и конверсии сероводорода из вод ного пара и сернистого ангидрида, возвращают обратно в печь с целью пневматической подачи сырь  и осуществлени  дуть  совместно с добавл емым чистым кислородом.The effluent gases, which after condensation of sulfur and conversion of hydrogen sulphide from water vapor and sulfuric anhydride, are recycled back to the furnace for the purpose of pneumatic supply of the raw material and blowing together with added pure oxygen.

Описываемый способ осуществл етс  следующим образом.The described method is carried out as follows.

Пылевидна  руда и необходимые флюсы подаютс  в печь пылевидного обжига оборотным газом, или вод ным паром через форсунку. Флюсы могут также подаватьс  непосредственно в нижнюю часть печ;-..The pulverized ore and the necessary fluxes are fed into the pulverized roasting furnace with circulating gas or water vapor through a nozzle. Fluxes can also be fed directly to the bottom of the furnace; - ..

Снизу печи подаетс  кислород, возможно больщей концентрациг., или в чистом виде.Oxygen, possibly more concentrated, is supplied from the bottom of the furnace, or in pure form.

При горении сульфидов в пылевидном состо нии развиваетс  высока  температура, достаточна  дл  поддержани  поступающих обожженных .материалов в жидком виде. Последние собираютс  на поду печи.When sulphides burn in a pulverized state, a high temperature develops, sufficient to maintain the incoming calcined materials in a liquid form. The latter are collected in a hearth furnace.
