Abstract
Inventia se refera la un procedeu de prelucrare a eluatilor uranifieri rezultati în urma elutiei cloro-carbonatice a onionitilor în tehnologia sodica de prelucrare a minereurilor uranifere, precum si a eluatilor acizi folositi în tehnologia cu acid sulfuric de valorificare a minereurilor uranifere. Conform inventiei, eluatii mentionati se ajusteaza pâna la pH=3-4, dupa care se contacteaza cu un cationit slab, care, la rândul sau, este eluat cu ajutorul unei solutii acide, din care se precipita concentratul chimic prin adaugarea unei baze, precipitat care se spala apoi cu o solutie de sulfat de amoniu. Prin purificarea cu anioniti a lesiei initiale si cu cantioniti a eluatului rezultat, se îndeparteaza atât cationii, cât si anionii, care însotesc uraniul în materia prima, iar spalarea cu (NH4)2SO4 îndeparteaza impuritatile antrenate.The invention relates to a process for the treatment of eutrophication uranifiers resulting from the onionite chlorine-carbon elution in uranium ore processing technology, as well as the acid eluates used in sulfuric acid technology for the recovery of uranium ores. According to the invention, said eluates are adjusted to pH = 3-4, then contacted with a weak cationite, which in turn is eluted with an acid solution, from which the chemical concentrate is precipitated by the addition of a precipitated base which is then washed with a solution of ammonium sulfate. By the anion purification of the initial and cannonites of the resulting eluate, both the cations and the anions, which accompany uranium in the raw material, are removed, and washing with (NH4) 2 SO4 removes impurities impregnated.
