Estimating the term…
The present invention relates to a method for dissolving metals by photocatalysis. A metal-containing material to be dissolved is dispersed in a mixed solution of photocatalyst-containing cyanide and organic chloride; then, a photocatalyst is added; next, an oxygen-containing gas or a substance which is capable of generating oxygen is introduced; and irradiation is applied for a period of time to dissolve metals. Compared with the prior method, the present invention is advantageous in moderate reaction condition, energy conservation, environmental protection, low cost, and convenient operation, and is suitable for mass industrial treatment on metal dissolution.
A method for dissolving metals by photocatalysis, characterized in that the method comprises steps of dispersing a metal-containing material to be dissolved in a mixed solution of photocatalyst-containing cyanide and organic chloride, and performing irradiation for a period of time to dissolve metals.
