Description
(54) СПОСОБ СОРБЦИОННОГО ИЗВЛЕЧЕНИЯ ЦВЕТНЫХ МЕТАЛЛСШ ИЗ АММИАЧНО-КАРБОНАТНЫХ РАСТВОРОВ(54) METHOD FOR SORPTION EXTRACTION OF COLOR METALS FROM AMMONIUM CARBONATE SOLUTIONS
Изобретение относитс к области гретной металлургии, в частности к гидрометаллургической переработке металлов.The invention relates to the field of greasy metallurgy, in particular to the hydrometallurgical processing of metals.
Известен способ сорбодонного извлечени цветных металлов из аммиачно-карбоштных растворов, содержащих 40-80 г/л аммиака и 40-60 г/л углекислого газа, с последующей промывкой водой и десорбцией цветных металлов растворами минеральных кислот. Основным недостатком известного способа вл етс высока стоимость ионита и относительно небольша обмешш емкость ионитов по цветным металлам . Целью изобретени вл етс расширение There is a known method for sorbodone extraction of non-ferrous metals from ammonia-carboste solutions containing 40-80 g / l of ammonia and 40-60 g / l of carbon dioxide, followed by washing with water and desorption of non-ferrous metals with solutions of mineral acids. The main disadvantage of the known method is the high cost of the ion exchanger and the relatively small amount of ion exchangers for non-ferrous metals. The aim of the invention is to expand
ассортимента высокоэффективных сорбентов и удешевление процесса.assortment of highly effective sorbents and cheaper process.
Это достигаетс тем, что сорбцию ведут на азотофосфоросодержащих ионитах с гругашровками аминометилфосфоновой кислоты.This is achieved by the fact that sorption is carried out on nitrogen-phosphorus-containing ionites with coarse aminomethylphosphonic acid.
По предлагаемому способу извлечение цветных металлов из аммиачно-карбоштных растворов ведут с помощью аминофосфорнокислых According to the proposed method, the extraction of non-ferrous metals from ammonia-carbosol solutions is carried out with the help of amino phosphoric acid
амфолитов типа АНкФ, содержащих а аминометилфосфоновые группировки:ampholytes of the type ANCF containing a aminomethylphosphonic groups:

Смолы этого типа обладают высокс оорОционной емкостью к ионам цветных металле, повьпиенной химической, терк ш 1ескай и механической прочностью, синтезированы из ;кгкодоступного сырь (полиэталенполнамши, метилакрилата ).Resins of this type have a high capacity for ions of non-ferrous metal, chemical, mechanical and mechanical strength, synthesized from kg of available raw materials (polyethylene hexafluoroamide, methyl acrylate).
Оюсоб осуществл етс следукацим образом .Ousobob is carried out in the following manner.
Аммиачно-карбонатньш раствор, содержащий медь, иикель, кобальт, мьпиь к и друтие зле менты, а также 50-80 г/л аммиака и 40- 60 г/л углекислого газа, при температуре 2070° С контактирует с аминофосфорнокислым амфолитом. После сорбции смола обрабатываетс 1-2 объемами воды на объем смолы. При этом значительна часть аммиака, карбоната и мьшгь ка удал ютс . Цветные металлы в данном случае не вымьшаютс .The ammonia carbonate solution containing copper, nickel, cobalt, copper and other zhelementa, as well as 50-80 g / l of ammonia and 40- 60 g / l of carbon dioxide, at a temperature of 2070 ° С is in contact with aminophosphoric acid ampholite. After sorption, the resin is treated with 1-2 volumes of water per volume of resin. In this, a significant part of the ammonia, carbonate and pulp are removed. Nonferrous metals in this case are not expired.
Десорбци цветных металлов осуществл етс 5-6 объемами (на объем смолы) 1-2 н растворами минеральных кислот, например сера (м кислотой. Регенераци и подготовка смолы к работе заклю|@етс в том, что ионит после де секции отмываетс от избытка кислоты 12 объемами воды.The desorption of non-ferrous metals is carried out with 5-6 volumes (per pitch of the resin) with 1-2 n solutions of mineral acids, for example sulfur (m acid. Recovery and preparation of the resin for operation) is that the ion exchanger is depleted from excess acid 12 volumes of water.
