铟M.Fickling,余楚蓉摘 要:<正> 1988年是世界需求持续增长的一年,尤其是日本达到了惊人的程度,因此,铟价从去年低于100美元/公斤暴涨到300美元/公斤.日本进口量与1987年相当,仍旧保持30吨,但日本产量却从27吨增到48吨.分布锢在地壳中的丰度估计是O.lppm,大约和银的含量相同,虽然不是一种特殊的稀有金属,但以低含量广泛分布在许多矿物中,所以回收量相当少.它趋向于富集在硫化矿里,尤其是闪锌矿.在目前闪锌矿是铡的主要工业来关键词:......
支持我国铟产业发展的对策研究邹俊义国家物资储备局研究所摘 要:日本和韩国把全球稀缺矿产资源--铟列为战略矿产资源储备.我国虽然是世界铟生产和出口大国,但铟产业结构不合理,生产集中度低,开采和加工过程中资源浪费严重,加之生产企业竞相压低价格出口,出口定价权长期被国外铟消费企业控制,致使我国铟产业陷入日本等国家设计的"低水平发展循环陷阱".因此,国家应加强对铟资源的保护,加大对铟生产技术研发的投入,建立我国铟资源的战略储备和商业储备,制定行之有效的鼓励政策,支持和促进我国铟产业健康快速发展.关键词:铟;铟产业;储备;......
