Advanced Separation Technologies for Extraction of Rare

Jul 26, 2012DESCRIPTION: A critical step in the extraction of elements from ore, especially rare earth elements that are found in complex minerals, is separation. Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral

Mineral Processing of Eudialyte Ore from Norra Krr

Aug 02, 2016Eudialytes are a nonconventional source for rare earth elements (REE). As the total REE content of eudialytes is relatively low, high-grade mineral concentrates have to be produced. The applicability of magnetic separation and direct selective flotation for the processing of eudialyte ore from Norra Krr (Sweden) was tested. The eudialyte in the used sample contains around 4 % of REE.
