Phosphate tailing is an extremely fine by-product during phosphate ore flotation. Due to the large quantities and relatively higher P 2 O 5 content, the phosphate tailings have been …
Rare earths are critical elements in our modern societies and the ever-increasing demand raises fears of supply risks in the coming years. This work dealt with the feasibility of …
An integrated hydrometallurgical process was used for the zinc leaching and purification from a zinc ore containing 9.75 wt% zinc. The zinc minerals in the ore were hemimorphite …
The optimization study of rare earth elements (REEs) leaching from electronic waste is imperative for industrial-scale development with cost-and energy-efficient processing …
This study aims to test three different acids (HCl, H 2 SO 4, HNO 3) for phosphate (PO 4− 3) extraction from waste fish bones ash using response surface methodology (RSM). Moreover …

Phosphate rock has been considered as one of the most significant secondary rare-earth resource, and the utilization of rare earth elements (REEs) in phosphate rock has attracted …
Phosphatic clay is a waste material produced during the beneficiation of phosphate ore, which likely poses severe environmental problems. In this study, a phosphatic clay …
Recently, efforts have been made to develop the extraction, recovery, and analysis of rare earth elements, especially the scandium Sc (III). This study describes the use of 15-crown-5 …
Artisanal mining is intensely carried out in developing countries, including Brazil and especially in the Amazon. This method of mineral exploration generally does not employ …
