The Production Of Critical Materials As By Products

The primary product of Bayan Obo is iron ore but Bayan Obo also produces much of the worlds REEs as a by product. In 2009 Bayan Obo produced 55000 metric tons of rare earth oxides REO 11. Bayan Obo produced more REEs than any other mine in the world. The primary processing of the REEs at Bayan Obo is by flotation and gravity separation.

Us4192738a Process For Scavenging Iron From Tailings

There is disclosed a process for scavenging iron from tailings produced by the flotation beneficiation of iron ore. This process includes the step of scavenging the flotation tailings using wet high-intensity magnetic separation WHIMS. There is also disclosed a process for increasing the recovery of iron ore in a flotation beneficiation process.

Flotation Characteristics Of Brucite And Serpentine

In alkaline condition experiments were taken to investigate the influence of different regulators on the flotation behaviors of brucite and serpentine when sodium oleate was the collector. The regulators used in experiments included sodium silicate tannin and calcium lignosulphonate. The results showed that sodium silicate had a great effect on the flotation.
