FIELD: mining engineering.
SUBSTANCE: invention can be used in recovery technology of sparse metals from slags of copper-lead-zinc sulphide ores. Germanium recovery method from solutions of complex ore processed slag opening includes autoclave opening with alkali liquor with concentration of 20 mass. % at temperature 200÷220°C, filtration with germanium and zinc solution separation from cake. One makes selective sorption of germanium with alkali concentration in solution 2-8 mass. % on weakly basic anion exchanger resin.
EFFECT: germanium selective sorption on weakly basic anion exchanger resin from high alkaline solutions and possibility of zinc oxide receiving with the help of carbonisation of zinc solution tempering its main salt.
