The ash free coal (Hyper-coal) and the by-product of the process (residue coal) were evaluated for the reduction materials of the nonferrous metal. The hard, dense lump carbonized product from Hyper-coal had high reactivity for silicon metal production and it was suggested that this material could be used for the production of high purity silicon metal. The residue coal from Hyper-coal process also had a high reactivity for reductant in the synthetic rutile production from ilmenite resources and it demonstrated the possibility to increase production rate and product quality from the existing synthetic rutile plants.
