Recycling Technology of Fly Ash Using Wet Flotation (Senosphere, Unburned Carbon, Magnetite, Silica, and Mullite)
Category Waste


1. Outline

 * Technology to recover useful resources from fly ash using wet floatation.


2. Characteristic

 * Separation of lightweight aggregates from fly ash slurry → gravity separation of fly ash slurry from which lightweight aggregates are separated → separation of slurry with high specific gravity and slurry with low specific gravity.

 * Extracting fine-powdered spherical fly ash which is melted and vitrified with high temperature in a boiler only with wet ore dressing without processing, and using it as various industrial raw materials.

 * Possible to efficiently purify useful resources from fly ash sludge without going through complex chemical treatment processes.
 - Improving eco-friendliness through non-chemical treatment processes.
 - Possible to apply to each applicable purpose because of the difference in specific gravity and thermal conductivity.

 * Recycling of waste resources by recovering unburned coal and utilizing it as fuel for power generation.
 - Possible to solve agro-ecological and natural ecological pollution problems around power plants due to the conventional landfill of mixed fly ash slurry.
