Abstract

Ushbu maqolada kobalt metalini ishlab chiqarishning zamonaviy ahvoli zahiralari va ishlab chiqaruvchi yetakchi mamlakatlar haqida ma’lumotlar diagramma va jadvallar ko’rinishida keltirilgan. Bundan tashqari rux ishlab chiqarishda hosil bo’ladigan kobalt saqlagan oraliq mahsulotlarni turlari va ularni kimyoviy tarkiblari, qayta ishlash texnologiyalarining texnologik sxemalari haqida batafsil to’xtalgan. O’zbekistonda ham birlamchi kobalt saqlagan xomashyo zahirasi mavjud emas ammo oraliq mahsulot Co-Ni keki rux ishlab chiqarishda hosil bo’lmoqda va bunda Co miqdori 1 - 2 % atrofida bo’ladi. Bu esa o’z navbatida ushbu xomashyoni qayta ishlab yiliga 1-1,3 tonnaga yaqin qo’shimcha ravishda kobaltni ajratib olish imkonini beradi.
