Reducing the environmental impact of blast furnaces

A problem here is that the red mud lowers the iron content in the blast-furnace batch. However, this effect may be compensated by reducing the content of fines in the batch, according to research on the chemical composition of Russian blast-furnace batch. The minimum iron content in the red mud at which such compensation is feasible is established.
