Abstract
O’zbekiston Respublikasida qimmatli metallarni ishlab chiqarish sanoatini salmoqli darajada kengaytirish ko’zda tutilgan. Hozirda qimmatbaho mettallarga bu darajadagi e’tiborning qaratilishi ularning davlat iqtisodiyotidagi o’ta muhim roli bilan uzviy bog’liq. Qimmatbaho metallar ishlab chiqarish sur’ati darajasi ko’p jihatdan murakkab oltin tarkibli rudalarni o’zlashtirishni ko’paytirishbilanoshirilishi mumkin. Oxirgi yillardagi oltin rudalari xomashyolari tarkibiy tuzilishidagi o’zgarishlar tahlili shuni ko’rsatadiki, texnologik jihatidan “sodda” oltin rudalarning, ya’ni standart sxemada an’anaviy usullar bilan samarali qayta ishlanuvchi rudalarning nisbiy miqdori yildan-yilga kamayib bormoqda. Murakkab oltin tarkibli rudalarga ishlov berish ancha takomillashtirilgan sxemalarni qo’llashni, boyitishning mexanik, gidrometallurgik, flotatsiya, kuydirish, pirometallurgiya, ionalmashunuv, tanlab eritishva boshqa usullarini uyg’unlashtirishni talab qilish bilan birga yuqori samaraliva unumli jihozlarni qo’llashni talab etadi.
