摘要
本文针对镍精矿、铜渣与一次合金氯化浸出镍溶液的净化和钴、铁的富集回收，就萃取体系的选择，流程设计、分离技术等进行了研究。用单一的Ｎ＿（２３５）（三辛胺）萃取体系同时去除溶液中的铁、铜、钴等杂质，用离子交换法去除溶液中的铅，净化后溶液可满足生产１号电镍的要求，镍收率大于９９％。钻溶液含钴大于ｕ０ｇ／Ｌ，Ｃｏ／Ｎｉ＞５６００，钴收率大于９７％。铁溶液含铁４０～７０ｇ／Ｌ，Ｆｏ／Ｎｉ＞１０００。本流程进行了萃取平衡试验，并用离心萃取器进行了台架试验和半工业试验，结果表明，本流程是切实可行的。
In this paper,a purification process for nickel chloride leach liquor from ores,copper converter slag and alloy has been proposed,Selection of solvent extraction systems,process deslgn, separation technology and so on have been studied.Fe and other impurities were removed by a single extraction system with trioctylamine. The process also included Co recovery, Pb removal by ion exchange, Research work is colnposed of extraction experim-nt ,bench-scale test and pilot test carried out in centrifugal contactors...
