Microwave treatment of a brown coal concentrate from mugunsk coal for the manufacture of sponge iron

Abstract

A technique for the production of a finely dispersed dry brown coal concentrate with the use of microwave energy is proposed to prepare a charge mixture for the manufacture of sponge iron. The advantages of this technique over analogous industrial processes are demonstrated. The results of experiments on the briquetting of the charge mixture of brown coal and iron ore concentrates without the use of an additional binding agent are described.
