Analysis of ores, slags and other oxides

Oxide materials are distinguished by the fact that the compound forms of the elements may be very different, depending on the many geological types. In general, various main components (greater than 10 weight percent) and trace concentrations (less than 0.01 weight percent) are present. The analysis must take this into account not only in the sample preparation (preparation of solutions) but also in the desired indication of results. 

Basically, the literature provides two dissolution methods sample preparation with sample weights of 0.2—1 g and large dilutions, or smaller sample weights with less dilution (III.B). The relatively large dilution, in general after a fusion [51], for the determination of main and lesser components, as for example in silicate analysis [2], the determination of Al, Ca, Mg, Mn and Si in slags [4], Si [55], Pb and Mn [143], and also Cd, Ca, Cu, Pb, Mg and Si in ores or iron sinter [97, 147] and Cr, Mg in refractories [93] is presently used in routine analysis.
