Extraction properties of naphthenic acids
Authors:
Abstract
The possibility of using naphthenic acids for the extraction of some non-ferrous metals has long been established, but more detailed studies of this extractant have been published only in recent years. Thus, A. Fletcher and his co-workers established the dependence of metal extraction by naphthenic acid solution in kerosene on pH value and showed the possibility of separation of some metals by this method. The research resulted in several patents for the practical separation of metals. This process was applied for the separation of copper and zinc from solutions obtained by leaching of pyrite cinders. The possibility of using naphthenic acids for the extraction of rare and rare earth metals has been investigated.
