A total of twenty-four isolates of actinobacteria from arsenopyrite, pyrite, polymetallic sulfides and magnetite from Peruvian mining zones have been used with the purpose of characterizing them by morphological, physiological ...

The mineral extraction sector is one of the main sources of economic development in Brazil, and the state of Minas Gerais is highly dependent on this industry. The main ores mined are iron and gold; the second is usually ...

Cyclic voltammograms and capacitance measurements are presented to characterize the mineral response at relatively moderate environmental conditions, pH 4.5 and T = 25degreesC. The experiments involve examining the rates ...
