Abstract
Способ переработки свинцовых и свинцово-цинковых сульфидных руд и концентратов, включающий определение состава свинцовых материалов, расчет необходимого количества флюсов и определение расхода кислорода на плавку, обжиг-плавку шихты в вертикальном факеле в атмосфере технического кислорода или воздуха, обогащенного кислородом, восстановление диспергированного оксидного расплава фильтрацией его через слой твердого углеродсодержащего материала с получением чернового свинца и цинковистого шлака, отстаивание шлака в электропечи, отличающийся тем, что, с целью увеличения извлечения свинца, плавку ведут при расходе кислорода, определяемому по соотношениюP/B = A • K,где P - расход кислорода (100% O), нм/т шихты;B - стехиометрический расход кислорода на окисление металлов, серы и углерода шихты, нм/т;A = 1,542 - 3,299 C- 7,972 C- 4,285 C+ 28,851 CO+ 14,657 CC+ 27,370 CC- 88,895 CCC;K = 1 + 0,965/Н,Н - высота шахты плавильной зоны, м;C+ C+ C= 1 - сумма концентраций в шихте кислых окислов C(SiOи AlO), основных окислов C(CaO и MgO) и железа C( в пересчете на FeO), в весовых долях.Method for processing lead and lead-zinc sulphide ores and concentrates, including determining the composition of lead materials, calculating the required number of fluxes and determining the oxygen consumption for smelting, roasting-smelting the mixture in a vertical torch in an atmosphere of technical oxygen or oxygen-enriched air, restoring a dispersed oxide melt filtering it through a layer of solid carbon-containing material to produce rough lead and zinc slag, settling the slag in an electric furnace, Due to the fact that, in order to increase lead extraction, smelting is carried out with oxygen consumption determined by the ratio P / B = A • K, where P is oxygen consumption (100% O), nm / ton of charge, B is stoichiometric oxygen consumption for oxidation metals, sulfur and carbon of the charge, nm / t; A = 1,542 - 3,299 C- 7,972 C- 4,285 C + 28,851 CO + 14,657 CC + 27,370 CC- 88,895 CCC; K = 1 + 0,965 / H, H - height of the smelting zone mine, m; C + C + C = 1 is the sum of the concentrations in the mixture of acidic oxides of C (SiO and AlO), basic oxides of C (CaO and MgO) and iron C (in terms of FeO), in weight fractions.
