Description

Известно выделение цветных металлов из силикатных раснлавов воздействием на них углерода.The release of non-ferrous metals from silicate tannins by exposure to carbon is known.

Предлагаемый сноеоб более совершенен по сравнению с известными подобными способами, так как он интенсифицирует процесс выделени  металлов. Это достигаетс  тем, что в расплав ввод т науглерожепный чугуп и процесс осуществл ют при температуре выше 1300°, поддержива  концентрацию углерода в чугуне посто нной, непрерывно раствор   в нем углеродосодержащие Д1атериалы.The proposed technique is more perfect as compared with the known similar methods, since it intensifies the process of metal extraction. This is achieved by introducing carbonaceous cast iron into the melt and the process is carried out at a temperature above 1300 ° C, keeping the carbon concentration in the cast iron constant by continuously dissolving carbonaceous D-materials in it.

По предлагаемому способу выделение цветных металлов осуществл етс  в обогреваемой печи путем контактировани  силикатного расплава обрабатываемого металла с чугуном, который насыщаетс  углеродом непрерывным растворением в чугуне углеродосодержащих материалов . При этом никель, кобальт, хром и марганец, выдел  сь из шлака, полностью раствор ютс  в чугуне, медь частично переходит в чугун и при ее избытке образует самосто тельный слой, а цинк, свинец и другие летучие элементы отгон ютс  в газообр.зную фазу и могут быть уловлены в виде возгонов. Скорость цементации металлов из шлака в случае применени  дл  этой цели углерода, растворенного в чугуне, в несколько раз больше, чем при использовании твердого углерода. При этом использование углерода также повышаетс , так как устран етс  его окисление воздухом, поскольку процесс протекает под слоем шлака на границе разделени  фаз расплавленный шлак - жидкий чугун.According to the proposed method, non-ferrous metals are isolated in a heated furnace by contacting the silicate melt of the metal being treated with cast iron, which is saturated with carbon by continuous dissolution of carbon-containing materials in the cast iron. At the same time, nickel, cobalt, chromium and manganese, separated from the slag, completely dissolve in the iron, copper partially passes into the iron and, in excess of it, forms an independent layer, and zinc, lead and other volatile elements are distilled off into the gas-phase. and can be caught in the form of sublimates. The rate of cementation of metals from slag in the case of the use of carbon dissolved in cast iron for this purpose is several times greater than when solid carbon is used. At the same time, the use of carbon also increases, since its oxidation by air is eliminated, since the process proceeds under the slag layer at the boundary of the separation of the phases molten slag - liquid cast iron.

Предмет изобретени Subject invention

Способ выделени  цветных металлов из силикатных расплавов воздействием на них углерода, отличающийс  тем, что, с целью интенсификации процесса, в расплав ввод т науглероженный чугун и процесс осуществл ют при температуре выше 1300°, поддержива  концентрацию углерода в чугуне посто нной и непрерывно раствор   в нем углеродосодержащие материалы.A method for separating non-ferrous metals from silicate melts by exposure to carbon, characterized in that, in order to intensify the process, carburized cast iron is introduced into the melt and the process is carried out at a temperature above 1300 °, maintaining the carbon concentration in the iron permanently and continuously carbon materials.
