Active components of HS consist of humic acid (HA), humus, ulmic acid, fulvic acid, humin and certain ...
متن کاملCoal fly ash as a resource for rare earth elements
Rare earth elements (REE) have been recognised as critical raw materials, crucial for many clean technologies. As the gap between their global demand and supply increases, the search for their alternative resources becomes more and more important, especially for the countries which depend highly on their import. Coal fly ash (CFA), which when not utilised is considered waste, has been regarded ...
متن کاملRare Earth Elements Profile
Definitions and characteristics The rare earth elements (REE) (sometimes referred to as the rare earth metals) are a group of 17 chemically similar metallic elements, including the 15 lanthanides, scandium and yttrium. The lanthanides are elements spanning atomic numbers 57 (lanthanum, La) to 71 (lutetium, Lu) (Table 1). The lanthanides all occur in nature, although promethium, the rarest, only...
متن کاملEnvironmental Review of Coal Ash as a Resource for Rare Earth and Strategic Elements
Recently, prices of strategic minerals and rare earth elements have been rising dramatically due to global supply shortages and increasing demands. These metals are integral components of advanced technologies, such as, cell-phones, wind turbines, permanent magnets, and semi-conductors. The relative scarcity of these valuable elements has prompted many companies to search for new mineral source...
