The separation of pure, individual rare earths from complex ores has presented extractive chemistry with one of its greatest challenges. During the first part of the 20th century, the only technique available for separating rare-earth mixtures was fractional crystallization. In one instance a rare-earth researcher was said to have devoted several years of his life to carrying out 20, 000.

Rare earth magnetic drums RED Rare earth magnetic rolls RER Wet high intensity magnetic separators WHIMS Examples of these separators are the Readings WHIMS manufactured by Mineral Technologies and Eriez WHIMS manufactured by Eriez. They are commonly used to recover reject ilmenite from HMC ahead of dry separation.
Bunting offers gravity, pneumatic, and center-flow in-line magnetic separation equipment. As material flows across the surface of a powerful rare earth magnet, the magnetic force captures and traps ferrous metal contamination, holding it against the face of the magnet to prevent it.

The attraction of Rare Earth Magnetic Separators Author John Elder Higher quality products, all at lower costs. These objectives are typically contradictory however, in the case of rare earth magnetic separation, they are, in fact, complementary. Since the first commercial unit was commissioned in 1982 in South Africa, rare earth.

The rare earth magnetic separator range achieves the most effective dry separation of paramagnetic minerals at high throughput rates. The range includes Rare Earth Roll RERS and Rare Earth Drum REDS Separators which are available in a range of configurations and sizes from lab units to full production units. Typical applications include.
Total rare earth oxide TREO of the REE-bearing mineral concentrates reached 45.0. The zircon concentrate, a by-product of this process, had a Zr grade of 42.8. Consequently, it was possible to produce concentrates by combining relatively simple separation processes compared to the conventional.

Compounding the difficulties of separation were a lack of good methods for identification and assessment of purity and a lack of knowledge of the number of rare earth elements that existed. The first rare earth element, yttrium, was isolated in 1794 by the Swedish chemist Johan Gadolin from a heavy black mineral, ytterbite, named for the.
