Coking coal 

Coking coal

Coking coal is essential to the manufacture of blast-furnace coke and foundry coke, which is used in steel production. Coking coal is characterised by its low volatile matter content and high swelling index. Based on its properties, coking coal can be divided into two groups:

  • semi-soft coking coal (or SSCC)
  • hard coking coal (or HCC)

Hard coking coal has better coking properties than semi-soft coking coal. Australian hard coking coal is regarded as the benchmark for quality.

Given that the ultimate consumer of PCI coking coal is the steel making industry, we started to classify its sales as coking coal as of 1 January 2012, in line with industry practice. PCI coking coal is a type of coal used in steel production that can partially replace coke in the process of solid iron ore melting in blast furnaces. The blast furnace design needs to be adjusted in order to accommodate PCI technology.
