A review on the enrichment of iron values of low-grade Iron ore

High gradient magnetic separation technology is a green production technology that has an unparalleled superiority in separating fine and weak magnetic particles. As the characteristics of poor, fine, and heterogeneous in weakly magnetic mineral resources (hematite, wolframite, rhodochrosite, etc.), the importance of Magnetic separation using these chemically-modified particles offers simplicity and overcomes many of the problems associated with conventional separation/preconcentration techniques (Wang et alPreconcentration and separation of ultra-trace beryllium using

Selective extraction of uranium from uranium–beryllium ore by

Both uranium and beryllium are very important strategic metals and have been applied to many fields, such as nuclear industries, atomic energy, metallurgical industries and telecommunications industries. When uranium and beryllium in the ore were leached simultaneously, a complicated downstream separation process was needed.
