Synthesis process of forsterite refractory by iron ore ...

2009-1-1 · Synthesis process of forsterite refractory by iron ore tailings S95 (2) The synthesis process can be separated into three steps when iron tailing are used to synthesize forsterite materials. First, magnesium iron sosoloid (Mg1-XFeXO) and magnesium metasilicate (MgSiO3) are produced; second, fayalite is produced and third forsterite is produced.

Copper Slag - an overview | ScienceDirect Topics

Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper concentrates now available.
