Interfacial modification of mineral surfaces using bio-colloids derived from sustainable resources with respect to froth flotation

Project Details


After fossil fues have been the main energy resource for the past 100 years, humankind has to face global warming and a warning poluttion of teh earth´s ecosystem. Therefore, the energy transition from fossil fuels to renewable energy resources is a main challenge of our time. However, this requires a new way to store electrical energy decentralized using lithium-ion-batteries (Li-B). These Li-B are made of elements such as lithium, cobalt and copper, which are difficult to process. In Finland, deposits exist which consist of minerals bearing these elements. This could be a chance for Finland to become a supplier of these elements when their processing can be guaranteed. The main process to obtain them is called flotation, which requires a mixture of partly toxic chemicals. We study a new kind of chemical, which is a by-product of the pulp and paper or food industry and thus sustainable and harmless, to separate minerals to obtain elements used for Li-B production in a prosperous way.
