Abstract
The invention provides a treatment method and device for a germanium-containing material, and the method comprises the following steps: an acid leaching process: carrying out acid leaching treatment on the germanium-containing material by using an acid solution in the presence of an auxiliary agent to obtain a germanium-containing leachate; an adsorption step in which the germanium element-containing leachate is brought into contact with an adsorbent resin for adsorption treatment to obtain a germanium element-loaded adsorbent resin; a desorption process: carrying out desorption treatment on the adsorption resin loaded with the germanium element to obtain a germanium-containing desorption solution; and an evaporation separation process: carrying out distillation treatment and rectification treatment on the germanium-containing desorption solution to obtain germanium tetrachloride. According to the method, the germanium product with relatively high purity can be obtained by simplifying the germanium enrichment process, and the production cost is reduced.
