Abstract
Przedmiotem wynalazku jest sposób selektywnego odzyskiwania jonów miedzi i kobaltu z roztworu wodnego zawierajacego mieszanine jonów miedzi i kobaltu, jony siarczanowe, i/lub jony chlorkowe, i/lub jony azotanowe, i/lub jony amonowe, polegajacy na odzyskiwaniu w kolejnych etapach ekstrakcji i reekstrakcji jonów miedzi i jonów kobaltu. W pierwszym etapie przeprowadza sie ekstrakcje jonów miedzi i jonów kobaltu z roztworu wodnego o pH w zakresie 1,5-6 zawierajacego mieszanine jonów miedzi i kobaltu, jony siarczanowe i/lub jony chlorkowe i/lub jony azotanowe i/lub jony amonowe za pomoca ekstrahentów z grupy hydrofobowych oksymów ketonów alkilowo-2-pirydylowych o wzorze ogólnym 1, w którym R oznacza prosty lub rozgaleziony lancuch alkilowy zawierajaca od 6 do 16 atomów wegla, rozpuszczonych w rozcienczalniku organicznym az do otrzymania roztworu wodnego zawierajacego jony kobaltu, a nie zawierajacego jonów miedzi oraz roztworu organicznego zawierajacego zwiazki kompleksowe jonów miedzi oraz zwiazki kompleksowe jonów kobaltu, natomiast w drugim etapie roztwór organiczny poddaje sie procesowi reekstrakcji jonów miedzi za pomoca roztworu wodnego zawierajacego jony szczawianowe, dalej otrzymany roztwór organiczny zawierajacy zwiazki kompleksowe jonów kobaltu poddaje sie procesowi reekstrakcji jonów kobaltu za pomoca roztworu wodnego kwasu solnego o stezeniu co najmniej 15, korzystnie 35%, a nastepnie otrzymane roztwory wodne poddaje sie procesom wydzielania metali.The subject of the invention is a method of selectively recovering copper and cobalt ions from an aqueous solution containing a mixture of copper and cobalt ions, sulphate ions and / or chloride ions and / or nitrate ions and / or ammonium ions, consisting in recovery in subsequent stages of extraction and re-extraction copper ions and cobalt ions. In the first stage, the extraction of copper ions and cobalt ions is carried out from an aqueous solution with a pH in the range of 1.5-6 containing a mixture of copper and cobalt ions, sulfate ions and / or chloride ions and / or nitrate ions and / or ammonium ions with the help of extractants from the group of hydrophobic oximes of alkyl-2-pyridyl ketones of general formula I, in which R is a straight or branched alkyl chain containing from 6 to 16 carbon atoms, dissolved in an organic diluent until an aqueous solution containing cobalt ions and no copper ions is obtained and an organic solution containing complex compounds of copper ions and complex compounds of cobalt ions, while in the second stage the organic solution is subjected to the process of copper ions reextraction with an aqueous solution containing oxalate ions, then the obtained organic solution containing complex compounds of cobalt ions is subjected to the process of cobalt ion re-extraction a solution will help with aqueous hydrochloric acid having a concentration of at least 15, preferably 35%, and then the obtained aqueous solutions are subjected to metal separation processes.
