Metal recovery method, metal recovery device, metal recovery system, and metal particle manufacturing method

摘要

A metal recovery method and a metal recovery apparatus are provided that recover metal from a solution in which the metal is dissolved at high efficiency and low cost. One metal recovery apparatus 100 of the present invention is a basic one containing ions of at least one element selected from the group consisting of gold, silver, copper, palladium, rhodium, platinum, iridium, ruthenium, and osmium. The reaction vessel 21 for bringing the first solution into contact with the silicon 90 and the recovery unit 12 for recovering the metal composed of the above-described elements deposited on the silicon 90 are provided.
