The coal classification employed in Canada is the ASTM ranking system that is based on the fixed carbon, and calorific value on the dry mineral matter free basis (dmmf). This system was adopted in 1938 and is a general guideline to classify different coal ranks. Table 1 lists coal rank classification underTypes, or "ranks," of coal are determined by carbon content. There are four types of coal, ordered from highest to lowest rank below. Anthracite, or "hard coal," contains the highest amount of carbon out of all coal ranks (86%-97%) 1. It has a brittle texture and lustrous sheen.اقرأ أكثر
