Coal & Coke
Coking coal is an essential ingredient in steel production. It is different to thermal coal which is used to generate power. Coking coal, also known as metallurgic coal, is heated in a coke oven which forces out impurities to produce coke, which is almost pure carbon.
West Cumbria coals are known to be high volatile, hard coking coal. They have:
• Very low ash levels (less than 3%) – thus reduced waste material
• Very low phosphorus (less than 0.01%) – a major positive for steel strength
• Very good coke characteristics – it performs well in the furnace
• Moderate sulphur (around 1%) – reduced by coal processing
The quality of the coking coal our mine is able to produce will be very important as the higher the quality, the greater the demand from steel producers looking to maximise their productivity. Tests from the area lead us to believe that we can extract high quality ‘hard’ coking coal, which is the most desirable. This means West Cumbria’s coking coal will be highly regarded by the steel manufacturers.
