Description
Изобретение относитс к гидрометаллургии цветных металлов, в частности к переработке шламов медеэлектролитного производства.The invention relates to hydrometallurgy of non-ferrous metals, in particular to the processing of sludge from copper electrolyte production.
Целью изобретени вл етс повышение извлечени никел .The aim of the invention is to increase the recovery of nickel.

Дл опыта берут навеску шлама 10 г и помещают ее в титановую чашку, служащую катодом. В качестве анода используют свинцовую пластину. Заливают в электролизер 100 мл раствора серной кислоты концентрацией 120 г/л, затем подключают электроды к источнику тока и провод т катодную обработку шлама при плотности тока 300 А/м2 и времени 1 ч. Затем шламовую пульпу выгружают и провод т аэрационное обезмеживание при 95°С в течение 3 ч при продувке воздухом . Опыты провод т на двух типах шламов, состав которых приведен в табл. 1.For the experiment, we take a slurry of 10 g and place it in a titanium cup that serves as the cathode. As the anode using a lead plate. 100 ml of a solution of sulfuric acid with a concentration of 120 g / l are poured into the electrolyzer, then electrodes are connected to a current source and the cathode cutting of the sludge is conducted at a current density of 300 A / m2 and a time of 1 hour. C for 3 hours while purging with air. The experiments were carried out on two types of sludge, the composition of which is given in table. one.
Степень извлечени меди и никел независимо от их содержани в шламе состав- л ет 96 - 98%. При осуществлении известного способа извлечение меди составл ет 88 - 90%, а никел 30 - 45% в зависимости от типа шлама.The degree of extraction of copper and nickel, regardless of their content in the sludge, is 96–98%. In a known method, copper recovery is 88–90%, and nickel 30–45%, depending on the type of sludge.

Дл опыта берут навеску шлама 10 г и помещают ее в титановую чашку, служащую электродом, второй электрод выполнен из нержавеющей стали. В качестве электролита используют раствор серной кислоты концентрацией 120 г/л объемом 100 мл. На первой стадии процесса титановый электрод со шламом подключают к отрицательному полюсу источника тока и провод т катодную обработку шлама при плотности тока 300 А/м2 и времени 1 ч.

For the experiment, we take a slurry of 10 g and place it in a titanium cup, which serves as an electrode, the second electrode is made of stainless steel. A 120 g / l sulfuric acid solution with a volume of 100 ml is used as an electrolyte. In the first stage of the process, the titanium electrode with sludge is connected to the negative pole of the current source and the cathode treatment of the sludge is carried out at a current density of 300 A / m2 and a time of 1 hour. Then the polarity of the electroscope unit is changed

тродов, т.е. титанова пластина со шламом становитс анодом, и ведут процесс анодного обезмеживани шлама при плотности тока 100 А/м2 в течение 2 ч. Опыты провод т на двух типах шламов, состав которых приведен в табл. 2.trods, i.e. A titanium plate with sludge becomes an anode, and the process of anodic bleaching of sludge is conducted at a current density of 100 A / m2 for 2 hours. Experiments are carried out on two types of sludge whose composition is given in Table. 2
В растворе, полученном после обезмеживани шлама, не обнаружены благородные металлы.No precious metals were detected in the solution obtained after de-mixing the sludge.
Таким образом, предлагаемый способ позвол ет повысить извлечение никел из шлама с 50 до 97-98%, получить дополнительное количество никел , обогатить шламThus, the proposed method allows to increase the extraction of nickel from sludge from 50 to 97-98%, to obtain an additional amount of nickel, to enrich the sludge
