Indiana Center for Coal Technology Research 6 COAL RANK Anthracite coal is a dense, hard rock with a jetblack color metallic luster. It contains between 86% and 98% carbon by weight, it burns slowly, with a pale blue flame very little smoke Bituminous coal (in Indiana), contains between 69% 86% carbon by weight
Due to the fact that Premus is one of the most tech nologically advanced and comp etitive processes used today in the production of ferrochrome it was the process selected for Xstrata''s new ferrochrome facility, Project Lion, that is due to be commissioned in the third quarter of 2006 in the Steelpoort Valley in Mpumulanga, South Africa. 1.

The balance of the energy requirement in the KWG process developed at XPS is provided by natural gas, which has a higher calorific value than coal, Consumption is very conservatively estimated at 80% of that of the overall Premus process, an estimated 136 kg gas per ton FeCr. This is based on: The lower operating temperature of the KWG process
work. Premus process has been found to be the lowestcost and most energyefficient ferrochrome smelting technology. The process is designed to reduce electrical energy consumption during smelting by partly reducing pelletized chromite ores in a rotary kiln using energy obtained from coal pulverization and hot gases generated from
