  2. 6. Characterization of Gold Pathfinder Minerals

    Author : Gabriel Kofi Nzulu; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this Thesis, I investigate the properties of artisanal small-scale gold mining concentrate samples from the Kubi Gold Project of the Asante Gold Corporation near Dunkwa-on-Offin in the Central Region of Ghana with a material science perspective.X-ray diffraction (XRD) is used to identify SiO2 (quartz), Fe3O4 (magnetite), and Fe2O3 (hematite) as the main indicator minerals in the mining site while contributions from pyrite, arsenopyrites, iridosmine, scheelite, tetradymite, garnet, gypsum, and other sulfate minerals were insignificant.

  4. 7. Minimisation of Chromium Leaching from Low-Alloy Electric Arc Furnace Slag by Mineral Modifications

    Author : Ida Strandkvist; Fredrik Engström; Rainer Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag; leaching; minerals; Process Metallurgy; Processmetallurgi;

    Abstract : Iron and steel are produced continuously as a vital part of modern life. The largest by-product of metal production is slag. Slag is an essential part of the production of steel since, in the furnace, the molten slag removes impurities from the metal. When the slag which consists of oxides, solidifies minerals form.
