矿浆中的难免离子对黄铜矿和方铅矿浮选的影响 总被引:3,自引:0,他引:3
通过分析去离子水浸泡矿石后矿浆中的难免离子组成,研究矿浆中发生变化较大的Ca2 ,Mg2 ,Fe2 ,Fe3 ,Cu2 ,Zn2 和AP 等离子对黄铜矿和方铅矿浮选的影响.发现这些金属离子在用乙基硫胺酯做捕收剂的体系中对黄铜矿的浮选基本没有影响,而对方铅矿浮选的影响分成3类,起活化作用的Cu ,起抑制作用的Al3 ,Fe2 ,Zn2 ,和Cu2 以及基本不起作用的Mg2 和Ca2 .对阳离子的抑制机理进行了探讨. 相似文献

Extracting rare-earth elements from coal could soon be economical in U.S.Extracted from the report of UNIVERSITY PARK,Pa.The U.S.could soon decrease its dependence on importing valuable rare-earth elements,according to a team of Penn State and U.S.Department of Energy researchers who found a cost-effective and environmentally friendly way to extract these metals from coal byproducts.Using byproducts of coal production from the Northern Appalachian region of the U.S.,the team investigated whether a chemical process called ion exchange could extract REEs in a safer manner than other extraction methods.Results show that ion exchange is more environmentally friendly and requires less 相似文献
