Amethyst is a purple variety of quartz (SiO2) that owes its violet color to natural gamma irradiation, iron impurities, and the presence of trace elements, which result in complex crystal lattice substitutions. It is considered a semi-precious gemstone, and just two centuries ago was considered to have a value on par with diamonds, sapphires, and rubies.

The hematite ores are interpreted to be due to hypogene enrichment of the itabirites, while the friable ores are the result of supergene leaching of silica and iron enrichment. The geological resource is stated at 1.3 Gt of hematite ore and 2.8 Gt of friable ores. ... • Concentrate thickener • Tailings dam. Traditionally, iron ore content ...

The high-purity hematite concentrate used in this study was kindly supplied by the LKAB (Luossavaara Kiirunavaara Aktiebolag) company in Sweden. The chemical analysis showed that the initial hematite powder contained about 97.91% Fe 2 O 3, 0.73% Al 2 O 3, 0.73% SiO 2, 0.26% TiO 2, 0.20% MgO, 0.022% MnO, and 0.088% P 2 O 5.

This study aimed to recover high-purity silica from hematite tailings (HTs) using superconducting high-gradient magnetic separation (S-HGMS) technology. This process involved converting silica into a silicone-rich concentrate and subsequently employing a fluorine-free mixed acid to leach the silicon …
