The Mineral Separation laboratory is designed for performing chemical cleaning and purification of minerals. The fume hood in the lab is suitable for using hydrofluoric acid, in addition to other more commonly used acids. Four hot-dog rollers that sit within an acid cabinet can be used to continuously roll up to 24 one-liter sample bottles.

Soil samples collected in the study area are placed in a plastic bag on site, sealed and labelled with a unique sample label. After sample storage, some pre-treatments have to be carried out before the physico-chemical investigation. Pre-treatment includes sample splitting, drying, sieving (< 2 mm for fine soil, see Soil Laboratory - Particle Size Analysis) and digestion. The sample is divided by a riffle divider or by quartering to the desired quantity. The samples are either dried in air …
