In Handbook of Stable Isotope Analytical Techniques, 2009. 8-5.4 ICP-MS Method. Sulfur in steel was quantitatively measured by Naka & Grégoire (1996) by the ETV ICP-MS technique. Because they used 34 S-enriched spikes (isotope dilution) in their procedure, the method is reported here. Sulfur was extracted from steel by dissolution (in aqua regia) and precipitation as As 2 S 3.

Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and

Coal Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
