SOLVENT EXTRACTION RECOVERY OF METALS USING QUINOLINE DERIVATIVE

摘要: SOLVENT EXTRACTION RECOVERY OF METALS USING QUINOLINE DERIVATIVE A novel procedure is described for stepwise, selective extraction of metal values selected from molybdenum, copper, cobalt and zinc, using a substituted 8-hydroxyquino-line as solvent reagent. By controlling the equilibrium pH other conditions, it possible to selectively extract molybdenum copper aqueous, acidic solutions containing these along with values. Where and/or zinc are also present, can be stepwise extracted same It was previously believed that 8-hydroxyquinolines were only over wide range.
