Introduction to Separation Index: Modelling of Rare Earth Element Extraction Complexity for Feasible Processing

With the increasing demand from industries, the efficiency as well as the sustainability in extracting Rare Earth Elemnt (REE) from its main resources (mainly mining) has become very challenging. However, there is no specific study has been conducted particularly in optimizing the sequence of the ex...
