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.

Secondary Sample Preparation

Fusions are carried out with a strong alkali to ensure total basic oxide conversion. The resulting acidified solutions are instrument-finished for required major analytes.

Three (3) acid digestions, HNO3; HClO3 & HF are carried out on samples for trace level analyses.

Oxide and sulphide specie differentiation is carried out by specific leach types, depending on the element with an instrument finish. Examples are Cu oxide or sulphide leaches with an AA finish.
