Review on leaching studies of rare earth metals from monazite. flotation. The escalating demand of rare earth metals (REMs) in various applications and their continuous depleting ores have laid emphasis to produce metals from their complex resources by developing energy efficient and eco-friendly processes. Present review Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in Minerals Free Full-Text Accessing Metals from Low-Grade

Rare earth (RE) processing is an environmental hazardous operation. Processed minerals often contain radioactive elements like thorium which occur together with the precious RE elements due to their chemical and physical similarities. Environmental contamination with thorium around RE mining and processing sites is an issue of The results show the material and energy requirement varies greatly depending on the type of mineral ore, production facility, and beneficiation process selected. They also show that the greatest loss occurs during mining (25–50%) and beneficiation (10–30%) of RE minerals. The total recovery of rare earth from the primary ore is aboutMaterial and Energy Requirement for Rare Earth Production
