A typical thermogram of the iron ore tailings sample is shown in Fig. 5 (4.76–2.38 mm). There is a thin peak at 50 °C ascribed to the water loss in kaolinite and the peaks at 100–130 °C are ascribed to the loss of water physically adsorbed on kaolinite and goethite. The two peaks between 175 and 310 °C are due to the dehydroxylation of crystalline goethite to hematite (2FeO·OH → Fe
Use of iron ore tailing from tailing dam as catalyst …
Iron ore tailings from tailing dams are materials that are primarily composed of haematite and silica. The contents and dispersion of this iron oxide relative to silica make this material an excellent catalyst for its application in Fenton-like processes. However, to use this material in a continuous flow process, a pelletizing step is necessary, which presents technological challenges due …
Tailings - Wikipedia
These tailings contain large amounts of pyrite (FeS 2) and Iron(II) sulfide (FeS), which are rejected from the sought-after ores of copper and nickel, as well as coal. Although harmless underground, these minerals are reactive toward air in the presence of microorganisms, which if not properly managed lead to acid mine drainage .

Base Metal and Iron Ore Mining - IFC
the ore is done on site, the tailings generated also have to be managed. Ores with a low metal con-tent, say, less than 0.4%, generate significant quantities of tailings. In certain mines where ores have high sulfur content, drainage from mine workings and waste heaps can become highly acidic and can contain high concentrations of dissolved heavy metals. This acid mine drainage (AMD) can have ...
