Soft coking coal
In response to the need to lower coal costs, coke producers worldwide have learned to use poorer quality coals in their mix. Several classifications have appeared: "weak coking coal", "soft coking coal", "semi soft coking coal" which basically cover three main types : high ash hard coking coals, high ash high volatile coals with poorer coking properties or mixed blends of overall poorer proterties. CBB can supply soft coals from Australia, South Africa, China and advise on coal selection and impact on coke quality.
