As the exploration know-how increases, equally important is the need of reducing exploration costs. The facilities and expertise of the applied mineralogy laboratory supports the on-going mineral exploration in house. GTK as well is pacing up in order to meet the diverse research requirements of mineral commodities producers and users. The lab extends to joint research works with other researchers in different companies and industries. Noble and base metals and industrial minerals are the key research areas, and the group exchanges know-how to update our research group in the current innovation and development of industrial practices, scientific findings and mineral separation methods.
Our services include
1. Process mineralogical studies of mineral deposits, e.g., noble and base metals, industrial minerals and raw materials and product quality issues
Apart from using conventional research methods, new technologies in sample preparation for e.g., high voltage selective fragmentation of ore samples have opened new avenues to collect unaffected mineral grains for detailed investigations.
2. Investigation of hazardous minerals in natural and man-made environments
Natural soils sometimes contain elevated contents of heavy metals that can constitute a risk to life. Noble sample processing methods enable to concentrate the chemically measured anomaly in to a mineral concentrate that can be studied to identify and quantify the hazardous mineral phases. This will add value to traditional risk assessment process.
3. Characterization of byproducts and recycled materials
Large volumes of electronic waste have been generated and due to short life cycle of the electronics the volumes are expected to grow considerably. The waste contains both valuable and hazardous substances. These materials need to be known to be handled and recycled in a safe way.
Case study: Oiva gold-quartz dyke in the Lapland granulite belt, Laanila, northern Finland.
Geochemical survey was conducted in the area to assess the risk of arsenic present in the soil, Pirkkala, Southern Finland.
