Abstract
PURPOSE: To obtain starting material for the manufacture of ferromanganese with favorable properties causing no reduction in degree of oxidation, no powdering phenomenon, etc. at a low cost of treatment by granulating Mn ore-base fine grains with a necessary amount of a hydraulic binder and water.
CONSTITUTION: To Mn ore-base fine grains is added ≥7% hydraulic binder such as Portland cement, and they are granulated while suitably adding water. The resulting pellets are cured for a necessary time. In ordr to provide crushing stength to the pellets used in an electric furnace in general ≥7% hydraulic binder is required, and in case of <7% binder, the pellets collapse and cause a powdering phenomenon. The usual water content is about 7W10%, and the curing time is about 3W4 days to about 1 week.
