PROCEDURE FOR EXTRACTION OF METALS OUT OF MINERAL RAW MATERIALS

摘要

FIELD: metallurgy. ^ SUBSTANCE: procedure for extraction of metals out of mineral raw materials consists in leaching crumbled source mineral material in not less, than two serially connected reactors and in mixing. Further, product of leaching is size-graded into sand and slime fractions. Sand fraction is leached in not less, than two serially connected reactors at mixing. Metals are extracted from phases of the slime fraction and product of leaching of the sand fraction. ^ EFFECT: raised degree of crumbled mineral raw material leaching, reduced power expenditures for processing, reduced volume of reactors, and increased efficiency of leaching. ^ 10 cl, 2 ex
