Mazkur maqolada volfram tarkibli metallurgik texnogen chiqindilarni ikkilamchi xomashyo sifatida qayta
ishlash orqali volfram minerallarini samarali ajratib olish texnologiyasi tadqiq etilgan. Boshlang‘ich xomashyoning mineral
va fazaviy tarkibi rentgen-fazaviy tahlil yordamida aniqlanib, foydali va gang minerallarning miqdoriy nisbatlari baholandi.
WC–Co psevdoqotishmalarining turli kislotali muhitlardagi elektrokimyoviy xatti-harakati o‘rganilib, kobaltning selektiv
erishi uchun maqbul sharoitlar belgilandi. Boyitish jarayonlarida magnit ajratish va flotatsiya usullari ketma-ket qo‘llanilib,
zarracha o‘lchami, magnit maydon kuchlanishi hamda flotatsiya reagentlari tarkibining WO3 ajralish darajasiga ta’siri tahlil
qilindi. Tajriba natijalari magnit ajratish yirik fraksiyalar uchun samarali ekanligini, mayda va ultramayda zarrachalarda
esa flotatsiya jarayoni ustunlikka ega ekanligini ko‘rsatdi. Oldindan desliming va mos reagentlar kombinatsiyasini tanlash
sheelitning selektiv ajralishini oshirib, yuqori sifatli konsentrat olish imkonini berdi. Olingan natijalar volfram tarkibli
texnogen chiqindilarni kompleks qayta ishlash va resurslardan oqilona foydalanish uchun ilmiy-amaliy asos yaratadi
