"The joint patent application by Nordic Mining and Institute for Energy Technology (IFE) for a new technology for extraction of alumina from aluminium/calcium-rich minerals has been approved by the Norwegian Industrial Property Office (Norw. Patentstyret)."
"Today’s alumina production is mainly based on production from bauxite resources through the Bayer process. With the new technology, the so-called “Aranda-Mastin process”, alumina can be produced from alternative mineral sources, and production can be done in a more environmentally friendly manner. In addition to alumina, precipitated calcium carbonate (PCC) and silica may be produced as by-products. PCC is a commercial commodity used as filler in paper, plastics and paint. Silica can be used as filler in car tyres and plastics, and in production of cement, among other applications.
The new multi-product process gives potential for almost full utilization of the mineral resource while reducing waste production. Furthermore, the process utilises approximately 500,000 tonnes of CO2 per million tonne of alumina. This CO2 can either be stored safely and/or utilised as part of commercial production of PCC. Additionally, this process does not produce any toxic waste."
