The Ironmaking Process

The four horizontal rotary kilns are the heart of the reduction process. The residual char (carbon) remaining after the coal was heated is used to achieve the chemical reduction of iron oxide to iron. A number of chemical reactions occur in the kilns because coal and ironsand are not pure substances like laboratory chemicals.
