内容記述 | Evaluation of vacuum melting as the refining process for crude copper was made by thermodynamic calculations, and some fusion experiments were carried out on a laboratory scale. Experimental results obtained show the trend similar to that predicted by thermodynamical survey. Lead and bismuth, which are hardly removed by the fire refining process, were found to be easily separated by evaporation. Contents of antimony and arsenic can be reduced to about one half of the initial values, but most of nickel, selenium and silver remain in the melt. Sulfur and oxygen are removed in the form of SO_2 gas, and either of the two elements (oxygen in ordinary crude copper) remains in the melt. The rate of degassing reaction proceeds rapidly in general. Impurities are more effectively eliminated by raising temperature and with a longer period of melting, and also by decreasing vacuum melting pressure. Specific gravity of copper metal obtained is about 8.8,while that of raw material is about 7. | |||||
