Abstract
1. Способ переработки мелкозернистых сульфидных свинцовых и свинцово-цинковых концентратов, включающий измельчение концентратов, приготовление шихты путем смешивания репульпацией в оборотной водной фазе концентрата, оборотных окисленных свинецсодержащих продуктов и измельченных известкового и кварцевого флюсов, нейтрализацию пульпы, отделение твердой фазы от жидкой, сушку полученной шихты, обжиг и плавку шихты во взвешенном состоянии в атмосфере кислорода с получением диспергированного оксидного расплава, восстановление расплава в слое твердого углеродсодержащего материала с получением свинца и цинксодержащего шлака, отличающийся тем, что, с целью повышения степени извлечения цинка в шлак, нейтрализацию пульпы ведут известковыми шламами очистки промышленных стоков от цветных металлов.2. Способ по п.1, отличающийся тем, что плавку шихты во взвешенном состоянии ведут при расходе кислорода 87 - 98% по отношению к его расходу на заданную степень десульфуризации.1. A method of processing fine-grained sulfide lead and lead-zinc concentrates, including grinding concentrates, preparing a mixture by mixing repulpable in the circulating aqueous phase of the concentrate, recycled oxidized lead-containing products and crushed lime and quartz flux, neutralizing the pulp, separating the solid phase from the liquid, drying the resulting lime charge, roasting and smelting the mixture in a suspended state in an oxygen atmosphere to obtain a dispersed oxide melt, recovery of the melt in the layer of solid carbon-containing material to produce lead and zinc-containing slag, characterized in that, in order to increase the degree of zinc extraction into the slag, the pulp is neutralized with limescale sludge from industrial wastewater from non-ferrous metals. The method according to claim 1, characterized in that the smelting of the charge in suspension is carried out at an oxygen consumption of 87–98% relative to its consumption for a given degree of desulfurization.
