<p>A system in which contaminants are removed from coal by organic action of the strains Thiobacillus ferrooxidans, Thiobacillus thiooxidants, Thiobacillus thioparus, Thiobacillus neopolitanus, Thiobacillus acidophilus, Euglenoids, Cyanochlorophyta in a predetermined sequence in separate processing stages to result in a clean coal which, when burned, causes less pollution and serves as a more efficient energy source. The removed contaminants are generally oxidized iron and sulfur compositions which may be convertible to useable forms.</p> |
