This article presents the results of experimental studies on the chemical and rational analyses of the material composition of gold-bearing ores from the Kauldy deposit, as well as on the cyanidation of initial technological samples. According to the chemical analysis of the average ore sample, the average gold content was 3.08 с/u and the silver content was 2.438 c/u. In the ore sample, the proportion of free, cyanide-leachable gold was 90%, and that of silver was 91.36%; gold associated with Sb and As minerals and compounds accounted for 2.9%, silver for 1.23%; gold associated with iron and manganese carbonates and hydroxides accounted for 0.32%, silver for 0.82%; gold associated with sulfides (pyrite, arsenopyrite) accounted for 6.45%, silver for 2.47%; gold occurring as fine inclusions within quartz, aluminosilicates, and other acid-insoluble minerals accounted for 0.32%, while silver accounted for 4.16%. Tests were carried out on the direct cyanidation of the initial ore and beneficiation products. The Jinchan reagent (PRC) was used as a leaching agent as an alternative to sodium cyanide. Based on the experimental results, the optimal conditions for gold dissolution were determined. When the ore was ground to a particle size of −0.044 mm, with a sodium cyanide concentration of 0.07% (1.4 kg/t) and a leaching duration of 36 h, gold extraction into solution reached 90%, while silver extraction reached 88.36%. Experiments using the Jinchan reagent demonstrated that results comparable to those obtained using sodium cyanide can be achieved. When the ore was ground to −0.044 mm, with Jinchan reagent concentration of 0.3% (6 kg/t) and a leaching duration of 24 h under selective leaching conditions, gold extraction into solution reached 91.55% and silver extraction reached 91.72%.
