Characteristics of a calcite "limestone"-marble from Macedonia, used as flux material [PDF]
Journal of Mining and Metallurgy. Section B: Metallurgy, 2003 The phase characteristics of calcite "limestone"-marble from Banjany area village (near Skopje, Macedonia) were examined by means of XRD, SEM microscope in polarizing and reflected lights, chemical, DT/TG-analyses. It was concluded as follows: - calcite (

Polycrystalline MnBi as a transverse thermoelectric material
AIP Advances, 2023 To assess the potential of polycrystalline MnBi as a transverse thermoelectric material, we have experimentally investigated its anomalous Nernst effect (ANE) by means of the heat flux method. We prepared MnBi samples by powder metallurgy; this technique

Effect of olivine as MgO-bearing flux on low- and high-alumina iron ore pellets
Journal of Mining and Metallurgy. Section B: Metallurgy, 2023 In the present study, the effect of MgO in the form of olivine flux on low- and high-alumina iron ore pellet mineralogy and pellet quality has been studied. Green pellets were prepared by varying the MgO level from 0 to 1.5% with a basicity (CaO/SiO2)
