Discussion

Research reports effective bioleaching of sulfide minerals for copper extraction, suggesting potential for pyrometallurgy.

Copper extraction reached 98.5% from sulfide minerals through bioleaching processes, indicating high efficacy.
Specific rates of nickel leaching were similar across all sulfide materials, with values around 59 mg/(g·d).
Analysis of bioleaching from nickel-copper and copper-zinc concentrates demonstrates feasibility for processing various ores.
Findings suggest commercial potential for high copper concentrates, which may be suitable for pyrometallurgical applications.

A.G. Bulaev (2025) studied this question.
