EXTRACTION METHOD OF PRECIOUS METALS FROM SOLUTIONS Russian patent published in 2014 - IPC C22B11/00 C22B3/24

Abstract RU 2505614 C1

FIELD: metallurgy.

SUBSTANCE: extraction method of precious metals from solutions involves contact of a solution with a sorbent applied onto a carrier with developed surface. Xanthogenate of non-precious metals, which is applied onto the carrier, is used as a sorbent. A filtering flexible plate material is used as a carrier. Filtering flexible plate material with the applied sorbent is rolled into a coil that is placed into a sorption column and contact is performed by passing initial solution through the coil.

EFFECT: improving selectivity of extraction and content of precious metals in a product by using available reagents and materials.
