leaching - Opis:
- The article presents the research results for the effectiveness of copper extraction from ores of the Satpayev deposit with complex, mixed composition bacterial leaching. The experiments with pre-acidification of copper samples were performed using biological oxidation by A. Ferrooxidans bacterial culture, adapted strain. Biochemical opening moes of mineral raw materials using A. Ferrooxidans bacteria of a particular strain adapted to the copper waste composition and capable of oxidizing sulfide and iron-bearing minerals were worked out. The optimal growth conditions for microorganisms in copper mineral pulp medium were established (temperature, pH, S: L.) The highest leaching efficiency, up to 88.65%, was observed in the experiments with preliminary bio-oxidation of samples by A. Ferrooxidans bacterial culture.
