About Coal – colonialcoal

Coke is obtained from hard coking coal, which must be low in ash since ash is retained in the coking process and would introduce impurities to the liquid. The coal must also be low in sulphur since only approximately one-third of the sulphur is released as gas in the coking oven. Sulphur is also a contaminant in the liquid metal.
