Microorganism for use in industrial processes ...

The basic reaction mediated by microorganisms is: 4FeSO4+2H2SO4+O2(electron receptor)➝2Fe2(SO4)3+2H2O. Ferric iron is required to oxidize the sulfide in the minerals, thereby releasing copper into the acidified solution. Thiobacillus ferroxidans is one microorganism with known utility in this regard.

COAL -- A Fossil Fuel

2010-1-19  Surface mining is used to produce most of the coal in the U.S. because it is less expensive than underground mining. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished,
