| titleOfInvention | Valuable metal extracting process |
| abstract | The present invention provides a kind of extracting copper and/or method of lead selectively from the acid solution containing manganese etc. in high concentration.The valuable metal extractant of the present invention is represented by following formula.In formula, R 1 And R 2 Represent identical or different alkyl, R respectively 3 Represent hydrogen atom or alkyl, R 4 Represent hydrogen atom or carry out the arbitrary base in addition to amino being bonded as aminoacid with α carbon.The most following formula has glycine unit, histidine amino acid unit, lysine unit, aspartic acid units or N methylglycine unit.Using above-mentioned extractant extracting copper and/or during lead, preferably regulate the pH of acid solution more than 1.0 and less than 5.5. |
