FREMGANGSMAATE FOR EKSTRAHERING AV METALL-KOMPONENTER FRA VANDIGE OPPLOESNINGER AV METALLSALTER, OG NYE METALL-EKSTRAKSJONSMIDLER. |
摘要 |
<p>Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyridine derivatives containing the substituent -(COX)A where X is the group -OR1 or -NR2R3 and n is 1, 2 or 3. R1 is a hydrocarbyl group containing from 5 to 36 carbon atoms and R2 and R3 are hydrogen or a hydrocarbyl group wherein R2 and R3 together contain from 5 to 36 carbon atoms. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containing ores such as chalcopyrite.</p> |
