Abstract

A homogeneous, ground mixture of natural limestone or slaked lime and a mineraliser are brought to a temperature of 800-1100 degrees C. and then gradually to 1400-1700 degrees C. Specifically the natural limestone has a high purity level and the mineraliser is an oxide of iron or vanadium.
