A hydrometallurgical process for the recovery of cerium from Khuren khad ore

A hydrometallurgical process for the recovery of cerium from Khuren khad ore

This study presents the recovery of cerium (Ce) from Khuren Khad ore by using the hydrometallurgical process. Several methods of leaching and precipitation were employed to investigate the recovery efficiency of Ce from the ore. According to the result, it is 4.8% of Ce contained in this ore sample....
