对矿物组成份复杂,含泥多,锡石结晶粒度细,单体锡石少,含铁高,锡铁致密结合,伴生金属多而品位低,呈分散状态赋存于铁、锰矿物中的锡矿石。为了提高选矿回收率,同时回收伴生金属,我们在总结生产实践经验及试验研究的基础上,提出了选冶结合生产多种产品的方案。现在,用回转窑高温氯化挥发工艺处理含锡1.2～1.5％的难选中矿,综合回收锡、铅、铜、锌、铟、铋、镉、银、铁和砷等十种元素,
The composition of the mineral complex, containing more mud, cassiterite crystal grain size, less small cassiterite, high iron, tin and iron dense combination of associated metals and more low-grade, was dispersed in the presence of iron and manganese minerals Tin ore. In order to improve the recovery rate of mineral processing and recover the associated metal, we put forward the plan of combining the production of many kinds of products by combining the production practice and experimental research. At present, the refractory medium containing 1.2-1.5% of tin is treated with the high-temperature chlorination volatilization process of rotary kiln to comprehensively recover ten elements of tin, lead, copper, zinc, indium, bismuth, cadmium, silver, iron and arsenic,
