Сернокислотное низкотемпературное автоклавное выщелачивание файнштейна

Abstract

Different options for the leaching process were considered, getting different composition of leaching products. Experiments were conducted using а model sample, which had the following composition, %: 62 Ni, 7,1 Cu, 3,7 Fe, 2,2 Co, 18 S. 1. Under atmospheric conditions, the process lasts 4-8 hours in comparison with 1,3-1,5 hour for autoclave. Under increased pressure of oxygen achieved high rate of extraction of valuable components were (%): 67 Ni, 99 Cu, 99 Fe.
