method of processing lead and lead zinc raw material

摘要

method of processing lead and lead zinc raw materials, including the balanced u043fu043bu0430u0432u043au0443 raw materials in the presence of u0444u043bu044eu0441u043eu0432 and negotiable u043fu044bu043bu0435u0439 in an atmosphere of oxygen to the u0437u043eu0432u0430u043du0438u0435u043c u0434u0438u0441u043fu0435u0440u0433u0438u0440u043eu0432u0430u043du043du043eu0433u043e oxide melt, the restoration of the melt in the filter consisting of the solid carbon run to obtain metal u0438u0447u0435u0441u043au043eu0433u043e lead and u0446u0438u043du043au043eu0432u0438u0441u0442u043eu0433u043e slag.protection of liquid products of melting and subsequent u043eu0431u0435u0441u0446u0438u043du043au043eu0432u0430u043du0438u0435 slag with the fact that, in order to improve the direct recovery of lead, lead recovery in a filter u043au0438u0441u043bu043eu0440u043eu0434u0441u043eu0434u0435u0440u0436u0430u0449u0435u0433u043e gas rate of 20 to 120 kg of oxygen for 1 ton of lead oxide produced in the filter with u043eu043au0441u0438u0434u043du044bu043c u0440u0430u0441u043fu043bu0430u0432u043eu043c, whereas the solid voss u0442u0430u043du043eu0432u0438u0442u0435u043bu044f support at 0.40 - 080 kg of carbon dioxide for 1 kg of the amount of oxygen contained in the u043eu043au0441u0438u0434u0435 lead and further input in a carbon filter with the gas.
