Document Type and Number:
Japanese Patent JP2014098188
Kind Code:
A
Abstract:
To extract a metal composition contained in the metal-containing inorganic product, to industrially reuse both the extracted metal composition and residual after extracting metal composition, to effectively utilize environmental resource, and to reduce environmental risk by a metal-containing inorganic product.
A dispersion is divided into an extracted solution and an extracted residual by a process of mixing a strong acid solution to a metal-containing inorganic product and dispersing the metal-containing inorganic product in the strong acid solution to obtain a dispersion (S1) and a process of heating the dispersion and irradiating ultrasonic (S2).
