Maqolada g'arbiv O’zbekiston oltin va oltin-kumush kortlarming ma'dan tarkibi va oltin nanomineralogivasi ko'rib chiqildi. 7 dona mineral va geokimyoviv ma’dan turlari ajratildi - /Au-W/Au-Bi-Te/Au-As/Au-Ag-Te/Au-Ag-Se/Au-Sb/ Au-Hg/ Har bir ma’dan turiga muayyan oltin birikmasi mos: nanooltin - Fe(AuAsS) - maldonit - petsit - fishesserit - aurostibit - Hg-oltin va ularga tegishli takrorlanmas tellurid, selenid, intermetallidlar, sulfotuzlar va sulfidlarning mikro-nanoansambllari. Konlarda, vertikal mineral va geokimyoviv taqsimlanish va eroziyaviy kesimga bog ’liq holda, rudaning 2 tadan 5 tagacha bo 'Igan birlashgan turlari uchravdi. Ma ’dan tarkibining, oltin birikmalari va lining mikro- nanoansambllarining o'zgarishi, ma ’danning texnologikxususiyatlariga va bovitish usullariga ta'sir qiladi.

Gold nanomineralogy and material composition of ores of gold and gold-silver deposits in Western Uzbekistan were considered. 7 mineral and geochemical ore types - /Au-W/Au-Bi-Te/Au-As/Au-Ag-Te/Au-Ag-Se/Au-Sb/Au-Hg/ - were selected. Each type corresponds to a specific ore gold compound: nanogold - Fe (AuAsS) - maldonite - petzite - fishesserit - aurostibite - Hg-gold and related non-recurring micro-nanoassemblies of tellurides, selenides, intermetallides, sulphosalts and sulphides. The fields depending on the vertical mineral and geochemical zoning and erosional trunca tion consist from 2 to 5 types of ores. Changing of the ore composition, gold compounds and its micro- nanoassemblies affect the technological properties and methods of ore dressing.
