Table 4 Classification of sulfur content in coking coal for metallurgical use. Sequence number, Grade name, Code, Range of total sulfur content on a dry basis (St,d) /%. 1 Ultra-low sulfur coal, SLS: <0.40; 2 Low sulfur coal, LS: 0.40–0.70; 3 Medium-low sulfur coal, MLS: 0.71–0.95; 4 Medium sulfur coal, MS: 0.96–1.20; 5 Medium-high sulfur coal, MHS: 1.21–1.50; 6 High sulfur coal, HS: 1.51–2.50
How is the price difference corresponding to these coking coals with different sulfur contents determined? Are there any data on this?
