Abstract

Ujawniono nowy sposób ługowania minerałów siarczkowych obejmujący ługowanie pokruszonej rudy w reaktorze zbiornikowym z ciągłym mieszaniem, w którym roztwór do ługowania jest podawany przy wartości potencjału oksydacyjno - redukcyjnego bliskiej górnej granicy odpowiedniej do ługowania, a wychodzący roztwór do ługowania opuszcza reaktor przy wartości potencjału oksydacyjno - redukcyjnego powyżej niższej granicy odpowiedniej dla ługowania rudy. Wychodzący roztwór ługujący, który opuszcza reaktor do ługowania przechodzi przez etap utleniania żelaza poza reaktorem do ługowania, przy czym utlenianie żelaza powoduje tworzenie się rozpuszczalnego siarczanu(IV) żelaza(III), który jest mieszany z zawracaną porcją wychodzącego roztworu po ługowaniu (53), co powoduje wzrost wartości jego potencjału oksydacyjno - redukcyjnego aż do wartości bliskiej górnej granicy zakresu potencjału redoks, który jest odpowiedni dla ługowania rudy.
