Изобретение относитс к цветной металлургии, в частности к пироме- таллургической переработке медных никельсодержащих штейнов.The invention relates to non-ferrous metallurgy, in particular to the pyro-metallurgical processing of nickel-containing copper mattes.
Цель изобретени - повышение пр мого извлечени меди и улучшение качества файнштейна.The purpose of the invention is to increase the direct extraction of copper and improve the quality of Feinstein.
rf Технологи способа состоит в следующем .rf Technology of the method is as follows.
Шлак с подшихтованным восстановителем (1-3%) и флюсом (2-5%) загружаетс в печь, после чего провод т расплавление шихты и выдержку расплава при 1350-1500°С. Вторичный никелевый шлак сливают из печи и после гранул ции (или охлаждени ) перерабатывают в виде холодных присадок на переделе конвертировани медно- никелевых штейнов в никелевом производстве .Slag with the charged reducing agent (1-3%) and flux (2-5%) is loaded into the furnace, after which the mixture is melted and the melt is aged at 1350-1500 ° C. Secondary nickel slag is drained from the furnace and, after granulation (or cooling), is processed as cold additives in the redistribution of the conversion of copper-nickel mattes in nickel production.

Пример 1. Масса шихты 1 кг, Состав, мас.%: шлак 95, известь 2, уголь 3, т.пл. 1350 С, выход сплава 20%, содержание в нем никел 10, меди 86.Example 1. The mass of the mixture of 1 kg, Composition, wt.%: Slag 95, lime 2, coal 3, so pl. 1350 С, alloy yield 20%, nickel content 10, copper 86.
Обедненный шлак содержит 16,2мас.% никел и 16,3 мас.% меди.The depleted slag contains 16.2 wt.% Nickel and 16.3 wt.% Copper.
Пример 2. Масса шихты 1 кг. Состав, мас.%: шлак 94, известь 5, уголь 1, т.пл. 1500°С, выход сплава 15% от загрузки исходного шлака.Example 2. The mass of the mixture of 1 kg Composition, wt.%: Slag 94, lime 5, coal 1, so pl. 1500 ° С, alloy yield 15% of the initial slag loading.
Сплав содержит 88% меди и 9,3 никел . Содержание меди и никел в обедненном шлаке составл ет 19,7 и 16,1 мас.%, соответственно.The alloy contains 88% copper and 9.3 nickel. The content of copper and nickel in the depleted slag is 19.7 and 16.1 wt.%, Respectively.
Пример 3. Масса шихты 10 кг Состав, мас.%: шлак 92, известь 5, уголь 3, т.пл. 1500СС, выход сплава 22% от. загрузки шлака. Сплав содержит 87% меди и 9,2% никел . Содержа (ЛExample 3. The mass of the mixture 10 kg Composition, wt.%: Slag 92, lime 5, coal 3, so pl. 1500CC, alloy yield 22% of. slag loading. The alloy contains 87% copper and 9.2% nickel. Containing (L

ние меди и никел в обедненном шлаке 14,1 и 16,0 мас.% соответственно.copper and nickel in depleted slag are 14.1 and 16.0 wt.%, respectively.
Преимущество предлагаемого способа заключаетс в повышении пр мого извлечени меди н медном производстве за счет снижени ее количества, отправл емой в никелевое производство . При переработке в никелевом производстве в результате уменьшени отношени меди к никелю в шлаке с 2,5 до не более 1-1,3 возрастает отношение никел к меди в файнштей- е, что положительно сказываетс на его качестве. Уменьшаетс переход меди в магнитную фракцию и никелевыйThe advantage of the proposed method is to increase the direct recovery of copper in copper production by reducing its quantity sent to nickel production. During processing in nickel production, as a result of a decrease in the ratio of copper to nickel in the slag from 2.5 to no more than 1-1.3, the ratio of nickel to copper in matte increases, which has a positive effect on its quality. Copper transfer to magnetic fraction and nickel decreases
