The aim of the paper is created the Life Cycle Assessment (LCA)/Life Cycle Inventory (LCI) under uncertainty of the production of rare earth elements (REEs), from the European sources, mainly neodymium, cerium and lanthanum obtained from secondary sources, considered now as waste. The European sources with the highest content in REE, were identified to be New Kankberg (Sweden), and data from the flotation and magnetic separation processes of the tailings were used in presented case study. Uncertainty assessment in...

The paper presents the results from studies carried out in the farming conditions. It has been found that with the application of rational norms of mineral and organic fertilizers used for growing various crops (barley, rape, flax, soybean), soil fertility could be stabilized and their effectiveness enhanced. The content of mineral nitrogen under rape crops was at the level of the control variant. Its content in the variant using liquid manure (biofertilizer) was somewhat lower than that of in the rotted manure - ...

Currently the Life Cycle Assessment (LCA) methodology is more and more frequently used as a tool for evaluating the environmental performance of products or services. Conducting the LCA is particularly important and valuable for a new product, process or technology. That is also applied for research on the innovative solutions or process proposals. The ENVIREE project funded from the ERA-MIN programme within the 2nd Joint Call aims at complete recovery process proposal of REE (rare earths elements) from tailings a...
