Trace Elements in West Virginia Coals

Tin (Sn) Summary Statistics

Tin averaged 2.20 ppm (± 2.68 ppm) in West Virginia coals with a histogram highly skewed toward low values showing a tail toward higher values and a maximum value of 27.00 ppm in the Sewickley coal. Despite published relationships between tin and mineral matter, tin correlated only slightly with ash yield and ash related elements such as zirconium (Zr), hafnium (Hf), niobium (Nb), silver (Ag), chromium (Cr) and vanadium (V).
