Ushbu tadqiqot Chodak oltin-boyitish fabrikasi tomonidan hosil qilingan texnogen chiqindilarda qimmatbaho metallarning taqsimlanishi, granulometrik xususiyatlari va mineralogik tarkibini o‘rganadi. Turli chuqurlik intervallaridan olingan namunalar kimyoviy, granulometrik va mineralogik tahlil usullari bilan tekshirildi. Natijalar oltin konsentratsiyasi 0.60 dan 1.68 g/t gacha, kumush konsentratsiyasi esa 4.35 dan 28.89 g/t gacha o‘zgarganini ko‘rsatdi. Au va Ag ning eng yuqori konsentratsiyalari 4a namunada aniqlandi. Granulometrik tahlil chiqindining asosan mayda zarrachalardan iboratligini, −0.071 mm fraksiyaning materialning asosiy qismini tashkil etishini ko‘rsatdi. Mineralogik tadqiqotlar pirit, arsenopirit, xalkopirit, sfalerit, magnetit, gematit va temir gidroksidlarini aniqladi. Oltin mayda dispers zarrachalar ko‘rinishida hamda sulfid minerallari bilan birikkan holda uchraydi. Topilmalar Chodak chiqindilarining qimmatbaho metallarning ikkilamchi manbai sifatidagi salohiyatini tasdiqlaydi va samarali qayta ishlash texnologiyalarini ishlab chiqish uchun asos yaratadi.
