The source of nearly 50 pct of the sulfur content of an average bituminous coal used by an electric utility is pyrite (FeS2); pyrite is a component that is not chemically bound to the coal and, therefore, can be removed by physical separation methods. Removing 50 to 70 pct of the pyrite would accomplish only a 25- to 35-pct reduction in …

The Pulverizer is a machine added by Thermal Expansion 5. It is used to turn a block of ore into two of its respective Dusts. The Dusts can then be smelted in any type of Furnace to produce Ingots at a 1:1 ratio. It has a chance of giving a secondary output, which varies between ores. The Pulverizer has one input (blue), a primary output (red ...
