Outline of Final Research Achievements

The hot-thermocouple method was applied for evaluations of the oxidation reaction of copper concentrate with silica sand and the phase separation of sulfide matte/oxide slag melts. The processes were monitored by a CCD camera through a microscope recorded by a personal computer. The quenched samples were analyzed by scanning electron microscopy. Copper slag granules cooled in air consisted of magnetite and fayalite phases with As and Pb elements concentrated in the residual SiO2-rich aluminosilicate non-crystalline matrix with a satisfaction of JIS K 0058-2 for the elution amounts of Pb and As in 1mol/L HCl aqueous solution. Viscosity of copper slag and synthesized FeO-SiO2 slag melts were measured by rotating cylinder method. Interfacial reactions of re-bonded magnesia-chrome refractory with FeO-SiO2 slag melt was studied under controlled oxygen partial pressure of atmosphere by the prediction of thermodynamically-stable phases and high-temperature reaction tests.
