Description
Изобретение относится к цветной металлургии и может быть использовано при переработке свинецсодержащих сульфидных концентратов. Целью изобретения является повышение извлечения свинца. Для реализации способа свинецсодержащий сульфидный концентрат .перед плавкой подвергают окомкованию при добавке щелочи с температурой 365-400°С в количестве 10—4252 от массы концентрата, далее проводят плавку со щелочью при 6ОО~7ОО°С с получением металлического свинца и щелочного плава. Общий расход'щелочи составляет 50-70% от массы концентрата. 2 табл.The invention relates to ferrous metallurgy and can be used in the processing of lead-containing sulfide concentrates. The aim of the invention is to increase the extraction of lead. To implement the method, lead-containing sulfide concentrate is pelletized before smelting with the addition of alkali with a temperature of 365-400 ° C in an amount of 10-4252 by weight of the concentrate, then melting is carried out with alkali at 6OO ~ 7OO ° C to produce metallic lead and alkaline water. The total consumption of alkali is 50-70% by weight of the concentrate. 2 tab.
