Kind Code:
A
Abstract:
To provide a method for recovering cadmium from cadmium-containing soil where cadmium can be efficiently recovered from a plant cultivated in cadmium-containing soil and adsorbed with the cadmium in the soil, and can be reutilized as a cadmium raw material.
A plant having cadmium absorbability is cultivated in cadmium-containing soil and is thereafter harvested. The plant is burnt, so as to produce incineration ash. The cadmium component comprised in the incineration ash is reduced and volatilized, so as to be recovered.
