Abstract

Silicate materials containing Ca, Fe and Mn are mixed with oxygen-containing Ca or Si material to bring the composition of the material to a molar ratio (CaO-3 P2O5) /Si O2 of between 2.5 : 1 and 1.7 : 1. The mixture is heated to a temperature to form a dicalcium silicate portion and an Mn and Fe oxide portion and the two portions are separated, e.g. magnetically after slow cooling. The separated Mn-containing portion may then be treated, in the form of a slurry, with acid to purify it further. The concentrate may then be mixed with lime, silica and carbon and smelted to produce spiegeleisen containing, e.g. Mn 34 per cent, C 6 per cent and the balance substantially all Fe. Alternatively the concentrate may be mixed with silica and carbon and smelted to produce a metal containing Fe with only a small proportion of Mn, the resulting slag being mixed with lime and carbon and smelted to produce a metal product of high Mn content, e.g. Mn 91 per cent, C 4 per cent and the balance Fe.
