Effects of CaO, Al2O3 and MgO on liquidus temperatures of copper smelting and converting slags under controlled oxygen partial pressures
TL;DR: In this article, phase equilibria of silicate slag systems relevant to the copper smelting/converting operations have been experimentally studied over a wide range of slag compositions, temperatures and atmospheric conditions.
Journal ArticleDOI
The Effect of CaO on Gas/Slag/Matte/Tridymite Equilibria in Fayalite-Based Copper Smelting Slags at 1473 K (1200 °C) and P (SO 2 ) = 0.25 Atm
TL;DR: In this article, the effect of CaO on the equilibria between the gas phase (CO/CO2/SO2/Ar) and slag/matte/tridymite phases in the Cu-Fe-O-S-Si-Ca system at 1473 K (1200°C) and P(SO2) = 0.25 atm.
Journal ArticleDOI
Analysis of product morphologies and reaction mechanisms on gaseous reduction of iron oxides
TL;DR: In this paper, the authors examined the relationship between product structures, and the mechanisms and the kinetics of reduction of iron oxides, showing that the structures and reaction rates can be explained through the occurrence of four principal mechanisms; continuous gas pore formation, dense metal layer growth, discontinuous metal layer breakdown and continuous coupled growth of metal and pores.
Journal ArticleDOI
The gaseous reduction of solid calciowustites in Co/Co2 and H2/H2O gas mixtures
TL;DR: The reduction of calciowustites has been carried out in CO/CO2 and H2/H2O gas mixtures at temperatures between 1073 and 1373 K as mentioned in this paper.
Journal ArticleDOI
The effect of the CaO/SiO2 ratio on the phase equilibria in the ZnO-“Fe2O3”-(PbO + CaO + SiO2) system in air: CaO/SiO2 = 0.1, PbO/(CaO + SiO2) = 6.2, and CaO/SiO2 = 0.6, PbO/(CaO + SiO2) = 4.3
