METHOD OF PROCESSING PERSISTENT GOLD-BEARING ORES, CONCENTRATES, MIDDLINGS, AND A REAGENT FOR IMPLEMENTATION OF PROCESSING Russian patent published in 2005 - IPC

Abstract RU 2262543 C1

FIELD: mining industry.

SUBSTANCE: group of inventions relates to a method involving bacterial oxidation of sulfides and introduction into the process of nutrient medium for cultivation of bacteria and subsequent dissolution of exposed gold. This nutrient medium is strontium-containing naturally occurring saline solution composed of, g/L: Cl^- 305.6-345.0, Br^- 9.6-10.6, I^- 0.004-0.12, HCO₃ ^- 0.33-0.63, Na⁺ 1.4-3.2, K⁺ 1.3-5.0, Mg²⁺ 26.7-41.3, Mn²⁺ 0.065-0.115, Sr²⁺ 0.62-1.12. Nutrient medium may further contain energy source.

EFFECT: simplified gold recovery process flowsheet.
