is the by-product of the coking
process, primarily carbon with varying concentrations of nickel, vanadium,
and sulfur, and produced
Coke / Carbon Residue as either chunks or
sand-like grains. Coke with relatively low metal and sulfur content is used
as a feedstock in the manufacture of anodes for aluminum and steel
production; coke with higher metal and sulfur concentrations is commonly
used as a coal substitute.
