It is very beneficial for separating valuable minerals from complex ore.
Developed by Dr. Ahmed Sobhy, the magnetic flotation hybrid separation process was used as a case study to upgrade El-Maghara coal with 27.21% ash. The optimized process reduced the ash content to approximately 7.8%, achieving recoveries and separation efficiencies of around 76% and 78%, respectively.
