A calixarene-based phosphoric acid extractant for rare earth separation
The calix [6]arene phosphoric acid appears to be one of the most powerful extractants currently available for rare earth extraction. Furthermore, the stoichiometry for the metal complex was examined by Job's method. The cyclic calixarene was found to form a ( 2 : 1 ) sandwich complex with rare earth metal ions in acidic media. Original language.

Heavy Media Separation Process (ferrosilicon) | DMS Powders
Dense Medium Separation (also called Heavy Media Separation) is a well-established density separation process. Dense Medium Separation (DMS) uses the characteristic differences in density of the input material to enact a gravimetric-based separation. Due to the robustness of the process, DMS can be used in the separation of minerals, ore …
