Abstract

1. Способ переработки бедного оловосодержащего сырья, включающий деарсенизирующий обжиг при температуре выше 600°С в присутствии углеродсодержащего восстановителя, восстановительную плавку огарка с получением олова и шлаков, фьюмингование шлаков с сульфидизатором, отличающийся тем, что, с целью снижения потерь олова, повышения комплексности использования сырья и сокращения выбросов вредных веществ в атмосферу, в качестве сульфидизатора используют сульфидный огарок деарсенизирующего обжига сульфидно-мышьяковистого полупродукта обогащения оловянного сырья.2. Способ по п.1, отличающийся тем, что сульфидный огарок вводят в шихту фьюмингования в количестве, обеспечивающем отношение серы к олову в шихте, равное (2,5-0,6):1.1. A method of processing lean tin-containing raw materials, including dearsenizing roasting at temperatures above 600 ° C in the presence of a carbon-containing reductant, reduction melting of the cinder with obtaining tin and slags, fuming slags with a sulfidization agent, characterized in that, in order to reduce losses of tin, increase the complexity of use raw materials and reducing emissions of harmful substances into the atmosphere, as a sulfidizer use sulfide calcine dearsenizing roasting sulfide-arsenic intermediate product Tin raw materials. The method according to claim 1, characterized in that the sulfide calcine is injected into the fusion mixture in an amount that provides the ratio of sulfur to tin in the mixture, equal to (2.5-0.6): 1.
