Document Type and Number:
Japanese Patent JP7401053
Kind Code:
B2
Abstract:
To provide: a gold recovery method which is easy to carry out and has a high gold recovery rate; a gold recovery agent capable of highly selectively recovering gold which is used for the recovery method; and a gold recovery apparatus used for the recovery method.SOLUTION: A gold recovery method of the present invention is intended to recover gold from a treatment target liquid containing gold ions. The method includes: a mixing step of obtaining a mixed solution containing a gold-containing ladder type cyclic compound by mixing the treatment target liquid containing the gold ions and a gold recovery agent containing a ladder-type cyclic compound under conditions of pH 6 or less; and a filtration step of recovering a residue containing the gold-containing ladder-type cyclic compound by filtering the mixed solution.SELECTED DRAWING: Figure 3
