Abstract

Изобретение относится к способу обработки шлака, образующегося при производстве черновой меди, получаемой непосредственно из концентрата в печи для плавления во взвешенном состоянии, такой как печь взвешенной плавки, с целью извлечения меди, при котором по меньшей мере часть шлака выщелачивают по меньшей мере в одну стадию.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to a method for treating slag formed during the production of blister copper, obtained directly from the concentrate in a suspension melting furnace, such as a suspended smelting furnace, in order to extract copper, in which at least part of the slag is leached in at least one stage The international application was published along with an international search report.
