查询词典 sulfide

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。
