Abstract
Изобретение относитс к цветной металлургии, преимущественно к металлургии меди, и может быть использовано в производстве товарной меди. Цель изобретени - уменьшение концентрации никел в рафинированной меди. Расплавленную медь обрабатывают реагентом, содержащим алюминий, при расходе алюмини 5,3-11,3 кг на 1 т исходной меди, после чего расплав окисл ют кислородом. 1 табл.The invention relates to non-ferrous metallurgy, mainly copper metallurgy, and can be used in the production of commercial copper. The purpose of the invention is to reduce the concentration of nickel in refined copper. Molten copper is treated with a reagent containing aluminum, at a consumption of aluminum of 5.3–11.3 kg per ton of raw copper, after which the melt is oxidized with oxygen. 1 tab.

Изобретение относитс к цветной металлургии, преимущественно к металлургии меди, и мо жет быть использовано в производстве товарной меди из черновой, получаемой конвертированием медных штейнов или черновой меди.The invention relates to non-ferrous metallurgy, mainly to copper metallurgy, and can be used in the production of commercial copper from draft copper obtained by converting copper matte or copper draft.
Целью изобретени вл етс уменьшение концентрации никел в рафинированной меди.The aim of the invention is to reduce the nickel concentration in refined copper.
Пример. Провод т рафинирование меди состава, %: медь 99,18, никель 0,52; свинец 0,06} сера 0,08; мьшь к 0,03; сурьма 0,04j железо 0,005; цинк 0,003 добавкой в ее расплав металлического алюмини . Часть опытов провод т с окислением расплава после его обработки алюминием (предлагаемый способ). Рафинирование осуществл ют в печи Таммана; масса навески меди составл ет 1,00 кг. Температура расплава во врем опытов измен етс в пределах 1375-1423 К. Расход воздуха (в пересчете на 1 т меди исходной) составл ет 43 м .Example. A copper refining of the composition is carried out,%: copper 99.18, nickel 0.52; lead 0.06} sulfur 0.08; Mish to 0.03; antimony 0.04 j iron 0.005; zinc 0,003 additive in its molten metal aluminum. Part of the experiments were carried out with the oxidation of the melt after its treatment with aluminum (the proposed method). Refining is carried out in a Tamman furnace; the weight of copper is 1.00 kg. The temperature of the melt during the experiments varies from 1375-1423 K. The air consumption (in terms of 1 ton of copper of the initial one) is 43 m.
Измен емые услови опытов и их результаты приведены в таблице.Variable conditions of the experiments and their results are shown in the table.
По сравнению с известным способсж рафинировани черновой меди предлагаемый способ повьппает чистоту анодной меди, прежде всего по концентрации никел , что обеспечивает повьше- ние катодной плотности тока и производительности электролизеров на 15- 20% и увеличивает выход меди по току на.2-3%.Compared with the known method of refining blister copper, the proposed method boosts the purity of anodic copper, primarily in nickel concentration, which increases the cathode current density and the performance of electrolyzers by 15–20% and increases the current yield of copper by 2–3%.
