高达10%返现  Oct 28, 2020  Abstract Currently, the most common fluxing additive to pellets is dolomite CaCO3 MgCO3, in which the magnesium oxide content can form from 17 to 22%. If the magnesium oxide in pellets increases, then it is necessary to increase the dolomite dosage. Thus, the iron content decreases, which entails a decrease in yield ratio at subsequent

Phosphorous cannot be easily removed by fluxing, so it is critical that the iron ore must be low in phosphorous. The Pampa de Pongo pellets contain only 0.004% phosphorous and therefore should be highly desirable to most end-users. Sulphur is a frequent contaminant in coal and sometimes in iron ore. Sulphur causes iron to be 'hot short ...

The Making of Iron Steel

2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).
