The paper outlines the effects of acid mine drainage on the ecology of the surface environment and describes the details of a laboratory test programme that investigated the actual role of microorganisms in the formation of acid mine water. An example of the corrosive effects of acid mine water on mine pumping equipment is given.
Further, vast increased quantities of coal and fossil fuels will be required in the coming decades both to sustain continued economic progress and to lift billions of people out of poverty. Coal was the essential energy source of the 20 th century and it will continue that role in the 21 st century. Just as the developed nations once relied on ...
Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
