Sometimes, when the separation methods such as manual or color sorting, gravity separation, magnetic separation, or flotation cannot fully meet the mineral separation requirements, the leaching method is used instead [89,90,91]. For example, in LPPO, it is difficult to obtain a high-grade beryllium concentrate by flotation when the beryllium ...
Magnetically-assisted chemical separation/preconcentration method for the analysis of beryllium from aqueous solutions was developed. According to this method several extractants were coated on certain magnetic microparticles to assist the extraction of beryllium from the aqueous solutions.

While magnetic separators offer substantial advantages, some downsides need consideration too: 1. Limited Applications. Magnetic separation performs poorly with non-magnetic or only weakly magnetic materials like gold and graphite. Using it as the sole method won't effectively process these ores.
Combined with susceptibility of volcanic rock determined from core samples, an improved algorithm for separation of potential field anomalies can increase the resolution of magnetic data.
