RE: Einstein- He -Ain't +CMK coal rank becareful what you are saying. you could be sued for misleading:
"The New Elk Mine was opened in 1951 by the CF&I Steel Company to provide metallurgical coking coal for its blast furnace iron and steel production plant at Pueblo, Colorado. The CF&I plant was converted to direct electrolytic reduction of steel in 1981 eliminating its need for coking coal and the mine was sold to Wyoming Fuels who continued operation of the mine through 1989; the coal preparation plant, which was built in 1984 to improve product coal specification, continued operating with coal from other nearby mines until 1996."
