New #horizon europe project coordinated by SIM2 KU Leuven (Peter Tom Jones & Olivier Namur).
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 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).
EMJM PROMISE - The consortium of the University of Oulu, Montanuniversität Leoben, University of Zagreb and University Tecnica Federico Santa Maria is looking for talented students for the Erasmus Mundus Joint Master in Sustainable Mineral and Metal Processing
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.
Oulun yliopisto paransi sijoitustaa Shanghain listalla merkittävästi. Viime vuonna olimme sijalla 75-100 ja tänä vuonna sijalla 51-75. Eteenpäin siis mennään. Ohessa linkki: https://www.shanghairanking.com/rankings/gras/2022/RS0226
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]
