Oulu Mining School Research Centre
The objective of Oulu Mining School is to create a nationally and internationally leading teaching and research unit for the mining sector. The establishment of the unit is based on the Oulu Mining School concept developed at the university, which is now expanding to an extensive expert hub in geology, ore prospecting, mining technology and beneficiation.
The Oulu Mining School research centre offers an extensive service concept for the needs of the extractive industry. In addition to determining geochemical services, such as precious metal analyses and ferrous iron, the services include dissolution and flotation laboratory services and, for example, sample preparation services in the form of concentrates, polishing and sawing of samples. The range of services also includes training in explosion planning and flotation.
