铟Stephen Briggs,寿永华摘 要:<正> 铟-极大部分存在于世界各地的硫化锌矿中,但也存在于某些锡,铅,钨和铜矿中.工业上铟主要是从铅锌熔炼厂的烟灰和从提纯硫酸锌而产生的含镉渣中回收的.根据美国矿务局估计铟资源略高于3000吨.关键词:......
铟J.G.Fife,余楚蓉摘 要:<正> 铟在地壳里与许多不同的硫化矿共生,闪锌矿或硫化锌含自然铟多达1%,虽然中等含量是在此值以下,或许是0.005%左右.铟的其他来源还有方铅矿或硫化铅,以及各种含铅-锌-铜的复杂矿.在这些矿和含关键词:......
铟余楚蓉摘 要:铟M.Fickling继稳定的1991年后因日本需求猛增使钢市场十分繁荣,用户需求的增加超过产量的增加,尤其是在加拿大,其结果使铟价再一次达到高度稳定,全年回落约10%.生产铟的产量,消费和库存目前均没有权威性的来源,公布的一些数据绝对是可能经过周密...关键词:......
铟M.Fickling,余楚蓉摘 要:<正> 1991年是铟市场在需求旺盛尤其是日本消费增加几年之后稳定的一年.生产和消耗均和1990年的水平大致相同.工厂库存因价格回落有适度增长.关键词:......
