The feasibility of processing low-grade copper-nickel ores by heap bioleaching was investigated. It found that an iron-oxidizing strain acidophilic microorganisms, Acidithiobacillus ferrivorans, is effective in the leaching sulfide from deposits Russia’s Murmansk region. Sulfide mineralization studied mineral feeds described using methods X-ray phase analysis and optical microscopy. In process ...
