摘 要:从古时的青铜时代到今高科技时代，锡的重要性和应用范围不断显现与扩大，成为先进技术中一种不可缺少的材料。由于锡资源日趋贫乏，今后将更加重视低锡、难选矿物的利用。炼锡原料将向多金属、低品位方向发展，综合利用将成为炼锡厂的重要课题。低品位锡矿或中矿的烟化炉硫化挥发、高温氯化挥发等工艺技术将会在生产实践中应用。本设计是依据“云锡氯化法”处理难选贫锡中矿，火法工序所得收尘沉淀，用氯化钠溶液进行浸出分离锡铅，最终得到氯化铅和锡精矿。设计的主要内容从物料平衡计算及其它冶金工艺计算、设备选型、主体设备设计、车间平面布置等几方面来设计氯化分离铅锡、年产锡精矿600t的生产车间。

ABSTRACT:From ancient times to today's high-tech era Bronze Age, tin show the importance and scope of application and to expand and become an indispensable technology of advanced materials. As the tin resources become increasingly scarce, the future will be more emphasis on low-tin, the use of refractory minerals. Refining of raw materials will be more metal tin, low-grade direction, tin smelting plant utilization will become an important issue. Low-grade tin ore in the furnace smoke volatile sulfide, high temperature chloride volatilization process technology will be applied in the production practice. The design is based on "YTC chlorination" treatment refractory poor tin ore, dust collection fire assay processes from precipitation, leaching with sodium chloride solution, separating tin-lead, lead and tin chloride finally get concentrate. Design of the main content from the material balance calculations, and other metallurgical process calculation, equipment selection, the main equipment design, plant layout and other aspects of separation of tin chloride to design, produce 600t of tin concentrate production plant.
