In this context, magnetic separation methods are instrumental in the mining industry, especially for extracting rare earth elements, leveraging the unique properties of different types of magnets. Separation Process Steps. Utilising the principles of magnetic properties, the separation process steps for rare earth minerals in South Africa involve precise techniques to …
Flotation is a common mineral processing method used to upgrade copper sulfide ores; in this method, copper sulfide mineral particles are concentrated in froth, and associated gangue minerals are ...
Flotation—a method that separates materials based on differences in their surface wettability—is a process applied for both mineral processing and recycling of REEs, especially when the particles are fine and/or a high-purity …
Many studies have been published in recent years focusing on the recovery of rare earth elements (REEs) from coal-related materials, including coal, coal refuse, coal mine drainage, and coal combustion byproducts …
The efficiency of a flotation circuit operation relies on several factors that are pertinent to mineral nature and structure (variability of ore feed, particle size, complex mineralogy, and morphology) as well as the type of instrumentation and operational parameters (design parameters, reagents, quality of process water, air flow rate, and ...
Rare Earth Elements (REEs) have emerged as crucial components in modern technology, playing a pivotal role in various industries due to their unique properties. As their name suggests, REEs are not abundant in the Earth's crust, making them valuable and sought after for numerous applications. Understanding the geology and mining of REEs is essential …

The distribution of rare earth elements varies significantly between rare earth ores and ionic clay deposits. This distinction is evident in Table 1 (Packey and Kingsnorth, 2016). Table 1 highlights that ionic clays have a higher presence of heavier rare earth elements, ranging from gadolinium oxide (Gd 2 O 3) to lutetium oxide (Lu 2 O 3), including yttrium oxide (Y 2 O 3).
