FIELD: metallurgy.
SUBSTANCE: invention refers to application of mono-disperse macro-porous chelate ion-exchange resins for sorption of metals from pulp in hydro-metallurgical processes, particularly, in so called processes "resin-in-pulp". Mono-disperse macro-porous chelate ion-exchanging resin has average diametre of granules within the range from 0.35 to 1.5 mm. Sorbed metals correspond to mercury, iron, titanium, chromium, tin, cobalt, nickel, copper, zinc, lead, cadmium, manganese, uranium, bismuth, vanadium, such elements of platinum group as ruthenium, osmium, iridium, rhodium, palladium, platinum and also such valuable metals, as gold and silver. Here is also disclosed the procedure for production of mono-disperse macro-porous chelate resin containing picoline-amine groups.
EFFECT: increased output of extracted metals and more efficient sorption of metals.
