The test result shows:(1) Concentration after grind finely, multi product configuration, regrind and reconcentratipn of sulphide iron ore, and firstly recovering tin and removing sulfide ore as possible as are available metholds to improve the grade and recovery of tin concentrate, simplify technology flowsheet and reduce production cost;(2) Intensifying the recovery of single stage concentration table is the key to concentration to concentration after grind firely and improving index. The recovery of fine tin is sure to further improve index;(3) Regrind and reconcentration of ferro-sulphur ore may recovery some tin.

试验研究结果表明：(1)细磨入选，多产品结构，硫化铁矿物再磨再选，能拿早拿、能丢早丢，预先脱出硫化矿物是提高锡精矿品位和回收率，简化工艺流程，降低生产成本的有效途径；(2)强化一段摇床的回收是细磨入选，提高指标的关键，细粒锡石的回收是进一步提高指标的根本保证；(3)硫铁矿物再磨再选也可回收部分锡金属。

A series of antimony mercaptide compounds which formula are Sb 〓 and Sb S (CH〓〓COOR 〓(R represents an alkyl or aryl, aralkyl, n=0～2) have been synthesized. A new synthetic method has been invented to solve the defect of abroad patent method which has complex technological conditions and singleness intermediate compounds. A new catalyst QL-1 and preactivated antimony trioxide and other means have been used to avoid neutralizing, washing, separating and other procedures of intermediate and simplifing process flow at the same time. According to this new technique, a series of antimony mercaptides and their intermediate products have been synthesized with high yield.

合成了结构为SbS(CH〓〓COOR〓及Sb〓（R为烃基或芳烷基，n=0～2）的一系列硫醇锑化合物，针对国外专利报道的合成工艺存在着工艺条件苛刻，同时需多步完成，操作复杂，而且中间体品种单一的缺陷，发明了一种一步法合成硫醇锑化合物的新工艺，采用QL-1催化剂，且将三氧化二锑预先活化，变固—液相反应为液—液相反应，同时可免除中间体的中和、洗涤、分离等工序，工艺流程简化，产品收率高，且能制得系列硫醇锑产品。

A mathematical model was developed to investigate the molten steel flow and decarburization process in RH vacuum degasser system under the action of electromagnetic field.
