乳状液膜技术自铜矿堆浸液回收Cu^(2+)的研究

Study on Recovering Cu 2+ From Copper Heap Leach Liquor by Emulsion Liquid Membrane Technology

采用Lix984N -L1 1 3B -煤油 -H2 SO4乳状液膜体系 ,对人工配制的含Cu2 +溶液和铜矿山的铜矿堆浸溶液 ,进行了提取Cu2 +的试验研究。试验结果表明 ,Cu2 +提取率 99 0 1 %,Cu2 +与Fe3+的分离系数达 3 96 79倍 ,有机相回用 9次对该乳状液膜体系提取Cu2

Lix 984 N-L113B-Kerosene-H 2SO 4 emulsion liquid membrane system was applied to make experimental study on extracting Cu 2+ from the artificially made Cu 2+ containing solution and from the mine's copper heap leach liquor.The results showed a Cu 2+ extraction rate of 99.01% and a coefficient of Cu 2+ separation from Fe 3+ of 39679 times.Nine recyles of organic phase had no evident effect on the extraction of Cu 2+ by this emulsion liquid membrane system.
