Document Type and Number:
WIPO Patent Application WO/2014/112222
Kind Code:
A1
Abstract:
[Problem] To expand the uses of byproduct ash from blast furnaces and contribute to the formation of a recycling-oriented society. [Solution] Byproduct ash from a blast furnace is separated into unburned carbon and ash, the separated unburned carbon is used as fuel, and the ash remaining after removal of the unburned carbon is used as a cement starting material. Zinc can be removed from the ash and used as a steel starting material. The byproduct ash from a blast furnace can be separated into unburned carbon and ash by adding water to the byproduct ash from a blast furnace to create a slurry (S), performing surface modification of the slurry, and using ore floatation to separate the post-surface modification slurry into a lipophilic component and a hydrophilic component.
