Iron Extraction

These processes involve mixing together the iron with controlled quantities of fluxes. Iron, limestone and coke are fed into the top of the blast furnace. The limestone is melted to become the slag, which removes impurities such as sulphur. The main fuel used in the blast furnace is coke. This is made by heating carbon in the absence of oxygen.

Coke in West Cumberland

Not all coal will form an adherent mass of coke, but that which is mined in West Cumberland can rightly be termed "coking coal". Prior to 1700, the production of iron from its own ores was achieved by mixing the ore with charcoal in a shaft furnace, and, after igniting, blowing air into the lower part of the furnace.
