8th International Conference on f-Elements (ICFE-8) location:Udine (Italy) date:26-31 August 2012
The rare earths are found in nature as mixtures of the different elements in certain ratios, which can show slight variations depending on the type of ore or geographical location. It is important that the market demands for the different rare earths are in agreement with the abundance ratios of these elements, to avoid surpluses of certain metals. Surpluses create imbalances of the rare-earths markets. It must be realized that the surpluses cannot be solved by lowering volumes of rare-earth ores that are mined, because this will cause a shortage of less abundant rare earths that are in high demand.
