俄罗斯提出一种从水溶液中萃取分离金属的新方法,称为“泡沫浮选萃取”。此法将溶剂萃取与泡沫浮选联用。在每种金属的特征ｐＨ值下,用有机酸萃取剂进行萃取,使萃取物形成泡沫,空气泡将萃取物相输送到泡沫层,同时与溶液混合。该法将高生产率和低成本的浮选与有选择性和残留金属 Russia proposed a new method for the extraction and separation of metals from aqueous solutions, called “froth flotation.” This method will be solvent extraction and foam flotation combined. At the characteristic pH of each metal, extraction is performed with an organic acid extractant to foam the extract, which delivers the extract phase to the foam layer while mixing with the solution. The law combines high productivity and low cost flotation with selective and residual metals
