STUDY OF NOBLE METALS IN AN ORE SAMPLE OF THE “ESHLIK I” DEPOSIT

Abstract

Improving the technology for extracting platinum group metals from technogenic
waste of the metallurgical industry, including conducting a number of studies in the following priority
areas: creating a methodological basis for improving the technology for extracting platinum group
metals from ores. and secondary technogenic raw materials; In order to create chemical technologies
for the enrichment and extraction of rare and precious metals from off-balance ores and various raw
materials, a detailed determination of their chemical and mineralogical composition is being studied.
In order to study the forms of gold in the ore sample of the Yoshlik I deposit, gravity and
flotation concentrates were produced from a sample of the original ore. Gravity enrichment
concentrates were previously studied on an Olympus SZX-7 stereomicroscope for the presence of
large and free particles of gold and intergrowths of a valuable component with other minerals, as
well as to determine the physical characteristics of one of the noble metals.
Technological and mineralogical characteristics have been studied for gold. For this purpose,
all grains of various gold minerals are combined into one group “gold”.
In the ore sample from the Yoshlik I deposit, gold is found mainly in native form. The fineness
of native gold varies from very low-grade, high-silver (510 standard units) to pure (1000 standard
units). The average gold standard is 890 conventional units. According to the results of phase
analysis, the main part of gold in ore samples from the Yoshlik I deposit is in cyanidated form –
89,88%.
