発明の名称 (英語) METAL COLLECTION METHOD AND METAL COLLECTION SYSTEM, AND SOLUTION REGENERATION METHOD AND SOLUTION REUSE SYSTEM 新技術説明会
発明の概要(英語) [Problem] To provide: a metal collection method and a metal collection system, whereby it becomes possible to collect a metal from a liquid metal waste with high efficiency and at low cost; and a solution regeneration method and a solution reuse system. [Solution] One embodiment of the metal collection method according to the present invention comprises: a deposition step of bringing a solution, which contains no fluoride ion or contains the fluoride ion in an amount of 0 to 8 mg/L exclusive and contains ions of at least one element selected from the group consisting of gold, silver, copper, palladium, rhodium, platinum, ruthenium and osmium, into contact with particulate silicon of which the entire or a part of the surface is covered with an insulating layer, thereby depositing a metal comprising the element onto the silicon; and a collection step of collecting the metal that comprises the element and is deposited on the silicon.
