Аннотация

The results of the leaching of the tailings from the heap leaching section with the aim of extracting
gold associated with sulfides are presented. A representative sample of the tailings of the heap leaching section was
selected and its chemical, phase, and mineralogical composition were studied. It was established that the test sample
contains 1.2 g / t Au. According to a rational analysis, by sorption cyanidation at a fineness of 95% class minus 0.071
mm, 76.09% of gold is extracted from a sample of heap leaching tailings, which is mainly (71.74%) represented by
intergrowths with ore and rock-forming components. The mass fraction of free (amalgamable noble metal is
insignificant (4.35%). The main reason for the persistence to sorption cyanidation is the close association of gold
with sulfide minerals. In the optimal mode of cyanidation of oxidation residues, 71.7 % of gold is recovered in 24
hours
