  • Utilization of sulphidic tailings from gold mine as a raw

    Utilization of sulphidic tailings from gold mine as a raw

    Apr 10, 2016 Mine tailings consist mainly of SiO 2, Al 2 O 3, and CaO. In addition, some iron oxide was seen — about 10 %. The content of sulphur as SO 3 was 5.2 %. Iron and sulphur originate from arsenopyrite and pyrite minerals which are the main minerals mined in this particular gold mine.

  • Using Gold Silver Tailings on the Elaboration of Ceramic

    Using Gold Silver Tailings on the Elaboration of Ceramic

    Apr 28, 2021 Abstract Ceramic foams were elaborated from gold-silver tailings and sodium silicates as foaming agent. The effects of the temperature and sintering time in a range of 850–880 C and 30–45 min, respectively, were evaluated. The foams obtained were characterized determining their apparent density, porosity percentage, volumetric expansion, mean pore size, and mechanical strength. The ...

    near processing plants. Clay slurry retains water that must be re‐used in processing. Fines and water can be separated with flocculants, but flocculants in recycled water interfere with oil sand processing. As of 2008, about 750 million cubic metres of fluid clay tailings exist within the tailings ponds near oil sands operations in Fort McMurray.

    Leaching of Trace Amounts of Metals from Flotation

    Oct 25, 2018 With decreasing ore grades, the tailings of mining operations are becoming of increasing interest as metal-containing secondary raw materials. The objective of the current work was to investigate chloride leaching of gold, copper, cobalt, nickel, and zinc present in the flotation tailings. In the current study, the effect of cupric ion as an oxidant (0–50 g/L) and NaCl (150–250 g/L) on ...

    Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
