Extraction process of copper and cobalt before flotation

for the extraction of copper and cobalt from sulfides-bearing ores. After obtaining a sulfide concentrate containing a sufficient grade of cobalt and copper by flotation, a thermal process (roasting) is applied to the concentrate to transform most of the cobalt and copper sulfide to a soluble sulfate, while iron
