How Metallurgical Coal Is Mined and Processed

Metallurgical Coal (C) is a energy mineral with global annual production of approximately 1.1 billion tonnes, primarily from Australia and United States. Typical ore grades range from N/A (coal quality measured by CSR, fluidity, volatile matter).

Mining Methods

Metallurgical Coal is extracted through the following methods, selected based on deposit type and geology:

• Underground longwall mining
• Open-pit/strip mining

Ore Types and Mineralogy

The principal ore types and mineral sources for Metallurgical Coal include:

• Hard coking coal - HCC
• Semi-soft coking coal - SSCC
• Pulverized coal injection - PCI

Processing and Beneficiation

Following extraction, Metallurgical Coal ore undergoes the following processing stages:

1. Washing and beneficiation
2. Coking in coke ovens

Environmental and Regulatory Considerations

Mining and processing of Metallurgical Coal must comply with environmental regulations governing water use, tailings management, emissions, and land rehabilitation. Increasingly stringent environmental standards are raising production costs but also driving innovation in cleaner extraction technologies. The social license to operate and community engagement have become critical factors in project development, particularly in Australia where 25% of global production is concentrated.
