Re-shaping the mineral industry
The growth of industrial economies, like for instance the Chinese and the Indian, led to a tremendous upward spiral of mineral Consumption. The demand is became so great that even low mineral concentrations and mining related waste can reasonably be considered ore deposits. This means the global mineral industry needs to be reshaped.

Deposit types and metal associations
Major ore deposit types and related high-tech metal associations
EU critical raw materials occur in genetic associations with common industrial and other high-tech metals e.g. • In, Ga with Zn • Te, Se, Co with Cu • REE with Fe • PGM with Cr and/or Ni

Critical raw materials central to EU ecomomy
•Raw materials are fundamental to Europe’s economy, and they are essential for maintaining and improving our quality of life. At the heart of this work is defining the critical raw materials for the EU’s economy. These critical raw materials have a high economic importance to the EU combined with a high risk associated with their supply. •The first criticality analysis for raw materials was published in 2010 by the Ad-Hoc Working Group on Defining Critical Raw Materials. Fourteen critical raw materials were identified from a candidate list of forty-one non-energy, non-food materials In the 2013 exercise fifty-four non-energy, non-food materials were analysed.
Green and low-carbon technologies & products
• Low carbon technologies require that the correct resources are available. Many wind turbines designs use magnets containing rare earth elements (REE), and solar panels and energy efficient lighting rely on metals such as silicon, tellurium and indium, amongst others
• Exhaust emissions from internal combustion engines are managed through catalytic converters containing platinum group metals
• Most of the environmental technologies and applications (e.g. photovoltaic cells, electric and hybrid vehicles) allowing energy production from renewable resources will use, so called, high-tech metals (e.g. REE, PGM, niobium, lithium, cobalt, indium, vanadium, tellurium, selenium) that were derived or refined from minerals, which Europe is strongly import dependent on
Major supplying countries of the EU Critical Raw Materials
World primary supply of the 54 candidate raw materials
World primary supply of the 20 critical raw materials
EU primary supply across all candidate materials is estimated at around 9%. In the case of critical raw materials, supply from the EU sources is even more limited.

Named deposits are subjects of active exploration
Economically feasible projects are progressing in Sweden (Norra Kärr) and Greenland (Kringlerne and Kvanefjeld) with a total potential (resources and reserves) of all three together in the order of 30 million tones REO.

•Any EU interests in the Pacific or other international waters? •Any marine REE exploration potential in European seas? •What about Blue Growth challenging actions under H2020?
Belts of REE exploration potential
•Even in the case of 100% recycling efficiency there will never be able to meet the increasing supply demand for most of CRM and REE. •Carbonatites and alkaline rocks may be of high priority but other types such as the granitic pegmatite IOA & IOCG ones need to be explored more efficiently. •Regional scale REE exploration approach could be the interpretation of genetic models linked to continental rifting •Distribution of REE (total, HREE, LREE and individual elements) occurrences in Europé •Reserves and resources in Europe and in individual countries
The trend in Europe is the same as in the rest of the world since 1960s, showing that REE mining projects are mainly related to primary deposit types associated with carbonatites and alkaline igneous rocks, compared to prior to 1950 when most of the bulk REE production derived from monazite-bearing placers.
Europe needs to focus on more effective exploration of critical MRM including REE
It all starts with understanding where critical mineral raw materials deposits occur, how they are formed, and how they can be sustainably extracted!
and Innovation is needed in
the whole value chain as many REE-based critical products are available as by-products of primary mined mineral resources
Both primary and secondary resources, in terms of re-use of by-products and mine wastes/tailings should be explored, evaluated and exploited
