Investigation of Freeze-Linings in Copper-Containing Slag Systems: Part I. Preliminary Experiments
TL;DR: In this paper, the formation of freeze-linings is studied under controlled laboratory conditions using an air-cooled "cold-finger" technique for Cu-Fe-Si-Al-O slag at equilibrium with metallic copper relevant to the industrial copper smelting processes.
Journal ArticleDOI
Investigation of Liquidus Temperatures and Phase Equilibria of Copper Smelting Slags in the FeO-Fe2O3-SiO2-CaO-MgO-Al2O3 System at PO2 10−8 atm
TL;DR: In this article, phase equilibrium experimental data in the FeO-Fe2O3-SiO2-CaO-MgO-Al 2O3 system at oxygen partial pressure of 10−8m within the range of temperatures and compositions directly relevant to copper smelting was provided.
Journal ArticleDOI
Phase equilibria in ferrous calcium silicate slags: Part IV. Liquidus temperatures and solubility of copper in "Cu2O"-FeO-Fe2O3-CaO-SiO2 slags at 1250 °C and 1300 °C at an oxygen partial pressure of 10(−6) atm
TL;DR: In this article, the solubility of copper in slag was evaluated and discussed for the ferrous calcium silicate system (described by the "Cu2O"-FeOO-Fe2O3-CaO-SiO2 system) by fitting the experimental values to a second-power polynomial in terms of CaO/SiO 2 and SiO2/Fe compositional parameters.
Journal ArticleDOI
Reduction of solid wustite in H2/H2O/CO/CO2 gas mixtures
TL;DR: In this article, the reduction of dense wustite in H2/H2O/CO/CO2 gas mixtures has been carried out at temperatures between 1073 and 1373 K.
Journal ArticleDOI
Stability Criteria for Product Microstructures Formed on Gaseous Reduction of Solid Metal Oxides
TL;DR: In this article, a range of different solid oxide and metal product morphologies can be formed on gaseous reduction of metal oxides by considering established criteria for the stability of moving interfaces in a thermodynamic potential gradient.
