ANNOTATSIYA
Ushbu ish Xonjiza koni misli polimetall rudalarini flotatsion boyitishda yangi
mahalliy flotareagentning texnologik samaradorligi va ehtimoliy fizik-kimyoviy ta’sir
mexanizmini kompleks baholash uchun ishlab chiqilgan na’munaviy tadqiqotdir.
Model tajribalarda ruda tarkibi, reagent dozasi, pulpa pH qiymati, yanchilish darajasi,
flotatsiya vaqti va pulpa zichligining Cu tiklanishi hamda konsentrat sifatiga ta’siri
ko‘rib chiqildi. Mexanizmni asoslash uchun adsorbsiya, zeta-potensial va kontakt
burchagi ko‘rsatkichlari kiritildi; FTIR, XPS va SEM–EDS esa tasdiqlovchi
instrumental usullar sifatida tavsiya qilindi. Sintetik dataset bo‘yicha 100 g/t atrofidagi
reagent dozasi, pH≈8.0 va P80≈106 µm sharoitlari yuqori Cu recovery bilan
bog‘langan. RSM yondashuvi reagent dozasi va pHning o‘zaro ta’sirini statistik
baholash uchun taklif qilindi.
