(54) СПОСОБ ВЫЩЕЛАЧИВАНИЯ СУЛЬФИДНЫХ РУД И КОНЦЕНТРАТОВ(54) METHOD FOR LEASTING SULFIDE ORES AND CONCENTRATES
Результаты опыта сравнивают с опытом по подаче воздуха без озонировани . Концентраци меди в растворе после опыта с озонированием достигает 0,56 г/л, трехвалентного железа 0,8 г/л, а .без озонировани соответственно 0,1 и 0,2 г/л. При этом йе обнаружено сколько-нибудь заметно концентрации озона в окружающем воздухе .The results of the experiment are compared with the experience of air supply without ozonation. The copper concentration in the solution after the experiment with ozonation reaches 0.56 g / l, trivalent iron 0.8 g / l, and without ozonization, respectively, 0.1 and 0.2 g / l. At the same time, no ozone concentration was detected in the surrounding air.
Пример 2. Выщелачивание руды ведут в услови х примера 1 при повышении концентрации озона в воздухе до 1,5, а количества воздуха до 0,3 на 1 т руды. Концентраци меди в растворах повышаетс до . 0,62 г/л, а трехвалентного железа до 1,0 г/л. Озона в окружающем воздухе не обнаружено.Example 2. Leaching of ore is carried out under the conditions of example 1 with an increase in the concentration of ozone in the air to 1.5, and the amount of air to 0.3 per ton of ore. The copper concentration in the solution rises to. 0.62 g / l, and ferric iron to 1.0 g / l. Ozone in ambient air is not detected.
Пример 3. Выщелачивание руды ведут в услови х примера 1, количество поданного озонированного воздуха ,5 мЗ/ч на 1т руды, а содержание озона в нем V 2,5%. Процесс практически идет, также как и в примере 2Example 3. Leaching of ore is carried out under the conditions of example 1, the amount of ozonated air supplied is 5 m3 / h per 1 ton of ore, and the ozone content in it is 2.5%. The process almost goes, as in example 2
в то же врем в окружающем воздухе обнаружено количество озона, превышающего санитарно-гигиеническую норму в 5-12 раз.At the same time, the amount of ozone detected in ambient air is 5–12 times the hygienic rate.
Пример 4. Выщелачивание ведут в услови х примера 1.Уменьшение количества поданного воздуха до 0,05 м/ч на 1 т руды, а содержание озона в нем до 0,5% значительно снижает интенсивность выщелачивани . Концентраци меди в продуктивных растворах падает до 0,15 г/л, а трехвалентного железа до 0,3 г/лВ таблице приведены результаты экспериментов,Example 4. Leaching is carried out under the conditions of Example 1. Reducing the amount of supplied air to 0.05 m / h per 1 ton of ore, and the ozone content in it to 0.5% significantly reduces the intensity of leaching. The copper concentration in the production solutions drops to 0.15 g / l, and ferric iron to 0.3 g / l. The table shows the results of experiments,
Из таблицы и приведенных примеров видно, что процесс выщелачивани идет интенсивно и безопасно при подаче озонированного воздуха в количестве 0,1-0,3 м /ч на 1 т руды с содержанием озона в нем 1,0-1,5%.It can be seen from the table and the examples given that the leaching process is intensive and safe when supplying ozonated air in an amount of 0.1-0.3 m / h per 1 ton of ore with an ozone content of 1.0-1.5%.
Подача озона в продуваемый через РУДУ воздух интенсифицирует выщелачивание в 4-6 раз.The supply of ozone to the air blown through the ore intensifies leaching 4-6 times.
