The aim of the present research was to examine process bioleaching and application a combined for recovery copper nickel from industrial sand deposits. investigated sample sands finer than 0.1 mm in size contained 0.32% Ni 0.22% Cu. Industrial were processed by flasks on thermostatically controlled shaker. In addition, roasting experiments carried out with ammonium sulfate. An attempt also made...

Microbial solubilizing of metals in acid environments is successfully used in industrial bioleaching of ores or biomining to extract metals such as copper, gold, uranium and others. This is done mainly by acidophilic and other microorganisms that mobilize metals and generate acid mine drainage or AMD, causing serious environmental problems. However, bioremediation or removal of the toxic metals...

BACKGROUND Members of the genus "Ferrovum" are ubiquitously distributed in acid mine drainage (AMD) waters which are characterised by their high metal and sulfate loads. So far isolation and microbiological characterisation have only been successful for the designated type strain "Ferrovum myxofaciens" P3G. Thus, knowledge about physiological characteristics and the phylogeny of the genus "Ferr...

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 ...

The development of biocathodes is highly fascinating in microbial electrochemical technologies research. In this study, iron-oxidizing bacterium Acidithiobacillus ferrooxidans-based were developed under the constant polarization reactors at −0.2 V vs. Ag/AgCl with a pH 2. On 15th day 21-day batch experiment, A. biocathode produced maximum current density −38.61 ± 13.16 A m−2 when supplemented 1...
