由于铁电薄膜具有独特的电学、光学、热学、声学等性能，在光电子学、集成光学、微电子学等高新技术领域中有着广泛的应用前景，八十年代以来铁电薄膜的制备、表征和应用已经成为了世界范围新材料研究中的热点。

Furthermore, natural pyrite and pyrrhotite were succeeded to induce to produce troilite in laboratory.

由于陨硫铁具有比较特殊的物理性能，论文在上述研究的基础上，尝试利用黄铁矿、磁黄铁矿为原料合成陨硫铁。

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。

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。
