Analytical Services

Mintek’s Analytical Services Division (ASD) is a well-established inorganic analytical chemistry laboratory that specialises in geochemical and metallurgical analyses. We provide this specialised analytical service to the mineral, metallurgical and related industries, using state-of-the-art instrumentation for a variety of techniques.

Classical Chemistry

A wide range of classical analyses are done by volumetric (titrimetric), colourimetric, gravimetric and spectrophotometric techniques. These are useful for high-precision work, as well as for some difficult analyses, including speciation of elements. Analyses include:

  • Determination of total carbon and sulphur in solids, and oxygen and nitrogen in metals, by combustion;
  • Gravimetric analyses such as proximate analysis of coal, silicate and sulphate determination;
  • Routine water analysis (inorganic), including pH, TSS, TDS, conductivity, fluoride and toxic contaminants;
  • TCLP and acid rain extractions;
  • Determination of anions by IC;
  • Colourimetric determination of P, SiO2, ammonia, etc.; and,
  • Speciation analysis, including carbonate, S species, Cr6+ and Fe2+ / Fe3+.
