15/04/2019 · Additionally there are the strongly magnetic iron meteorites with the NiFe minerals kamacite and taenite. You might get a more relevant answer if we knew what you were using the magnet for. If you are only separating concentrates from say gold panning or looking for meteorites then a regular handheld magnet will do.

08/05/2017 · Hematite specimens that frequently display iridescence are described as "rainbow hematite" and "turgite" (figure 1). The latter term originated with the German mineralogist Rudolph Hermann, who coined it in 1844 to describe iron hydroxide specimens found near the Turginsk River in the Ural Mountains (Hermann, 1844).

Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of ...
