Title:
易揮発性金属の生産処理で用いる方法および炉構造
Document Type and Number:
Japanese Patent JP3574192
Kind Code:
B2
Abstract:
The invention relates to a method and furnace construction to be used in producing easily volatile metals from their sulfides. The furnace construction comprises two closely connected furnaces, a reduction furnace and a converter, which are operated at normal pressure, so that the material transfer therebetween is arranged to be carried out continuously at normal pressure through at least one channel provided in between the furnaces. As a result of chemical reactions taking place in the furnaces, the hydrostatic pressure in the furnaces changes. In addition, volumes of the melt layers in the furnaces change. Circulations caused by these changes through the channel at the same time bring about the recycling of sulfide matte needed in the process from the reduction furnace to the converter and recycling of the molten metal from the converter to the reduction furnace.
