Monpilai Hangsubcharoen. Jul 22 Innovative Design of Fine Coal Cleaning Circuits for Improved Sulfur Rejection The only apparent disadvantage of processing the underflow sample was On the other hand fine spirals were much superior to flotation for coal preparation the results indicate good possibilities to remove automatically the remaining shale from the coal e The case when only partial coal
The trouble with bituminous and the other "soft" coals is that they are not very "green". They don t burn nearly as clean as anthracite. They have a high sulfur content. I have to justify this pollution problem to myself by noting that I can see the smokestacks of two power plants from my front field.
