(54) СПОСОБ ИЗВЛЕЧЕНИЯ ЦИНКА ИЗ ОТХОДО.В(54) METHOD FOR EXTRACTING ZINC FROM WASTE.
IpacTBOp сливаетс и может быть вновь направлен на растворение окиси цинкаIpacTBOp is discharged and can be re-directed to dissolve zinc oxide.
Пример 1. Пыль/ содержащую (%)8 цинка; 21 железа; 11 двуокиси кремни ; 8,5 окиси Кальци ; 0,2 свинца; 22 углерода, подвергают выщелачиванию водным раствором гликокола . Отношение Ж:Т 15:1. Объем раствора 1500 мл. Вес навески 100 г.. Температура раствора 20с. Концентраци гликокола 15 г/л.Example 1. Dust / containing (%) 8 zinc; 21 iron; 11 silica; 8.5 Calcium Oxide; 0.2 lead; 22 carbon, leached with an aqueous solution of glycine. The ratio W: T 15: 1. The volume of solution is 1500 ml. The weight of the sample is 100 g. The solution temperature is 20s. Glycocol concentration of 15 g / l.
Результаты выщелачивани приведены в табл. 1.The leaching results are given in table. one.
Из приведенной таблицы видно, что с увеличением времени выщелачивани извлечение цинка в раствор . повышаетс . Максимальное извлечение при за 150 мин составл ет 94%. Пример 2. Дл определени вли ни температуры на степень извлечени цинка опыты провод т в течение 120 мин в интервале О-бО-с. О- ошение Ж:Т 15:1. Концентраци гликокола 15 г/л. Состав пыли тот ж Показатели выщелачивани приведены в табл. 2.The table below shows that with increasing leaching time, the extraction of zinc into solution. rises. The maximum recovery at 150 minutes is 94%. Example 2. In order to determine the effect of temperature on the degree of zinc recovery, the experiments were carried out for 120 minutes in the range O-bc. Condition F: T 15: 1. Glycocol concentration of 15 g / l. The composition of the dust is the same. The leaching rates are given in table. 2
Из таблицы следует, что с ростом температуры извлечение цинка в раствор повышаетс и достигает при за 2ч 93%.It follows from the table that as the temperature rises, the extraction of zinc into the solution increases and reaches 93% at 2 hours.
Из вышеприведенного следует, что предложенный способ выщелачивани окиси цинка водным раствором гликокола позвол ет извлекать окись цинка более простым способом, чем п известной технологии, так как используетс одно вещество вместо . Затраты по предложенному способу на растворитель значительно меньше, что делает способ более рентабельным . Это св зано с тем, что стоимость 1 кг растворител по предложенной технологии равна 18 руб., а стоимость 1 кг ди-(2-этилгексил)фосфорной кислоты по технологии прототипа 260 py6i Кроме того, предложенный растворитель не вл етс токсичным, легко регенерируетс .From the above, it follows that the proposed method of leaching zinc oxide with an aqueous solution of glycocol allows zinc oxide to be extracted in a simpler way than in the known technology, since one substance is used instead. The cost of the proposed method for the solvent is significantly less, which makes the method more cost-effective. This is due to the fact that the cost of 1 kg of solvent according to the proposed technology is 18 rubles, and the cost of 1 kg of di- (2-ethylhexyl) phosphoric acid according to the prototype 260 py6i technology. Moreover, the proposed solvent is not toxic, it is easily regenerated.
Выделение цинка из раствора возможно двум способами: выделение в виде чистого сульфида цинка (60-62% Zn) в специальном аппарате с помощью сероводорода; выделение в виде чистого катодного металла путем электролиза.Isolation of zinc from the solution is possible in two ways: isolation in the form of pure zinc sulfide (60-62% Zn) in a special apparatus using hydrogen sulfide; isolation in the form of a pure cathode metal by electrolysis.
