Anthracite
•
Anthracite is the most highly metamorphosed form of coal
•
It contains more carbon (>86%
1,2
)
than any other form of
coal and the least volatile matter
•
Metallurgical coals typically release volatile matter when
heated above 350 degrees
Celcius
, leaving behind ‘Coke’
which is used to reduce metal oxides to metal
•
Anthracite is used due to its high fixed carbon content,
largely used for reducing metal oxide ores and graphitizing
material for electrode paste
