重庆银矿垭口铝土矿锂的分布特征

文章通过对重庆银矿垭口铝土矿中锂元素的分布特征的研究,发现含矿岩系中锂含量普遍超过了工业综合利用的最低指标,具备良好的综合利用的基础条件;锂元素在铝土矿中的存在形式存在多种可能,或吸附或类质同象;从铝土矿中提取锂的工业化进程受到选冶技术的限制,降低铝土矿中提Li的投入与产出比,提高资源利用率,有效压缩成本是今后开展铝土矿综合利用研究的重要方向。

Distribution characteristics of lithium in Yinkuangyakou bauxite deposit, Chongqing

The study on the distribution characteristics of lithium in Yinkuangyakou bauxite deposit, Chongqing , shows that the lithium content in the ore-bearing rock series generally exceeds the industrial lowest index of comprehensive utilization thus can be recovered economically. There are several possible lithium occurrences in the bauxite, such as adsorption or isomorphism. Industrial extract of lithium from the bauxite is limited by the beneficiation and smelting technologies. Reduction of investment/production ratio, improvement of the utilization rate of the resources, effective compression of cost will direct the research of lithium comprehensive utilization in the future.
