SEMACRET project (Sustainable exploration for orthomagmatic critical raw materials in the EU) aims to find new ore prospecting methods.

17.2.2023 Kari Moisio /

The SEMACRET project is coordinated by Oulu Mining School at the University of Oulu, and the consortium is composed of 16 parties from 12 different countries including EU, South Africa, and UK. The EU and UKRI invest 6.67 M and 0.83 M Euro respectively, with a total budget of 7.5 M euros for the three year project, implemented from June 2022.

EXCEED Cost-effective, sustainable and responsible extraction routes for recovering distinct critical metals and industrial minerals as by-products from key European hard-rock lithium projects

Kari Moisio /

EXCEED is a Horizon Europe project with 15 partners. University of Oulu is participating to the project with research towards by-product recovery (Oulu Mining School), valorisation of industrial and residual minerals in construction materials (Fibre and Particle Engineering), and digital twin for model-based decision making (Environmental and Chemical Engineering).

AGEMERA – Kriittisten raaka-aineiden potentiaali Euroopassa: Uudet ketterät malminetsintämenetelmät ja mineraalijärjestelmien mallinnus

03.10.2022 Ilkka Hynynen / Oulun yliopisto , TTK, Oulu Mining School R&D Centre

AGEMERA pyrkii lisäämään eurooppalaisten kriittisten raaka-aineiden saatavuutta lisäämällä tietoisuutta ja tietoa CRM:ien mahdollisuuksista, roolista ja vaikutuksista vähähiiliseen talouteen siirtymisessä. Samalla se vahvistaa EU:n avointa strategista autonomiaa. AGEMERA luo uutta tietoa ja innovatiivista teknologiaa, joka ohjaa kriittisten mineraalien ympäristöystävällisempää etsintää.

Comminution of lithium bearing pegmatites in a Hugger crusher based on a free crushing method

28.6.2022 Ilkka Hynynen / Oulun yliopisto , TTK, Oulu Mining School R&D Centre

Introduction Comminution in mineral processing is very energy intensive. For example, in ball milling energy efficiency is below 1 %. Valuable minerals are lost as ultrafine particles, which are generated when the ore minerals are crushed by arbitrarily directed loading during comminution. In addition, the fracture surfaces of mineral particles have physically and chemically changed because of wear and oxidation, making their further processing difficult and limiting application of dry and energy-efficient processes. The “Hugger crusher” brings a new concept of comminution, which allows a new way to load, crush and mechanically separate solid materials. The Hugger comminution technique is a promising technology to be used for developing more sustainable dry processing, froth flotation, chemical leaching, and bioleaching methods. The controlled formation of microcracks in mineral particles enables more sustainable comminution and classification of ore minerals with less water, energy, and chemicals. The formation of microcracks during the Hugger crushing is based on a phenomenon called “free crushing”. In the free crushing, the rate of feed is such that the crushed material passes freely through the double converging crushing unit without a contact between liberated particles (Figure 1). During the free crushing and slow compression, microcracks are formed at the natural boundaries of mineral crystals. This prevents the formation of ultrafine particles and reduces energy consumption.[1][2][3]
