Description
Изобретение относитс к области цветной металлургии, в частности к способам переработки сульфидных материалов, например медных,никелевых , в жидкой ванне. Известен способ переработки суль фидных материалов в конвертере на дутье, обогащенном кислородом. Известен способ непрерывной плав ки сульфидных материалов, включающи загрузку их, продувку ванны расплава кислородсодержащим газом через сопла в присутствии углеродсодержащего топлива с образованием сульфидной и окисленной фаз и выпуск расплава. Однако известный способ обладает р дом недостатков: низка производительность , пр мое извлечение меди не превышает 60%, низка скорость разделени штейна и шлака, способ требует предварительной сушки или гранул ции концентрата. По предложенному способу плавку ведут при удельном расходе сульфидных материалов 1,0-3,5 т/ч на один квадратный метр площади ванны с обр зованием надфурмен-ной и подфурменно зон расплава и при поддержании соотно1иени сульфидной .и окисленной ф в надфурменной зоне от 0,2 до 0,4 и подаче кислородсодержащего газа в толщу расплава с напр женностью дуть 10 - 20 1 т расплава в мин, что обеспечивает возможность переработки концентратов без предварительной сушки и кускового сырь , позвол ет интенсифицировать процесс плавки, повысить скорость отделени штейна от шлака и извлечение металлов . Предложенный способ осуществл етс следующим образом. При вдувании в расплав кислородсодержащего газа при напр женности дуть 10 MVT расплава в мин и загрузке 1,0 т/м сульфидных материалов в надфурменном слое создаетс эмульси с содержанием сульфидов 20%, а при увеличении загрузки до 3,5 т/м дол сульфидов в эмульсии возрастает до 40%. Количество сульфидов в надфурменном слое можно уменьшить за счет увеличени напр женности дуть до 20м ут расплава в мин и соответствующей при этом интенсификации перемешивани расплава . При содержании сульфидов в надфурменной зоне менее 20% энергично переокисл етс железо в ш.паке и РОЗThe invention relates to the field of non-ferrous metallurgy, in particular, to methods for processing sulphide materials, for example copper, nickel, in a liquid bath. A method for processing sulfide materials in a converter enriched with oxygen enriched is known. There is a known method of continuous melting of sulphide materials, including loading them, blowing the bath of the melt with oxygen-containing gas through nozzles in the presence of carbon-containing fuels to form the sulfide and oxidized phases and releasing the melt. However, the known method has several disadvantages: low productivity, direct copper extraction does not exceed 60%, the rate of separation of matte and slag is low, the method requires predrying or granulation of the concentrate. According to the proposed method, the smelting is carried out at a specific consumption of sulfide materials of 1.0-3.5 t / h per one square meter of bath area with the formation of over-and-underfurmly melt zones and maintaining the ratio of sulphide and oxidized f in the over-tempering zone from 0 , 2 to 0.4 and supply of oxygen-containing gas to the thickness of the melt with the intensity of blowing 10 - 20 1 t of melt per minute, which makes it possible to process the concentrates without pre-drying and lumpy raw materials, allows to intensify the melting process, increase the speed separated matte from the slag and metal extraction. The proposed method is carried out as follows. When oxygen-containing gas is injected into the melt with a voltage of 10 MVT of the melt per minute blowing and 1.0 t / m of sulphide materials are loaded, an emulsion with a sulfide content of 20% is created in the over-furman layer, and when the load increases to 3.5 t / m emulsion increases to 40%. The amount of sulphides in the overburden layer can be reduced by increasing the intensity to blow up to 20m melt per minute and correspondingly intensify the melt mixing. When the content of sulphides in the suprafurm zone is less than 20%, iron in the shpak and ROZ is strongly oxidized
