Ushbu keng qamrovli tadqiqot laboratoriya sharoitida boshqariladigan holatda kaliy xloridning ammiak sulfati eritmalari bilan o‘zaro ta’sirining termodinamik va kinetik jihatlarini o‘rganadi. Tadqiqotning asosiy maqsadi – qo‘sh tuz hosil qilish usuli orqali kaliy sulfat olish jarayonini optimallashtirishdir. Eksperimental ishlar O‘zbekiston hududidagi Tyubegatan foydali qazilma konidan olingan flotatsion kaliy xlorid hamda yuqori tozalikdagi ammiak sulfati eritmalari asosida olib borildi. Tadqiqot davomida qattiq va suyuq fazalar o‘rtasidagi nisbat, reaksiya harorati hamda jarayon davomiyligining kaliy sulfatga aylanish jarayonidagi kimyoviy tarkibga ta’siri tizimli tarzda o‘rganildi. Natijalar shuni ko‘rsatadiki, optimal qo‘sh tuz hosil bo‘lishi 1:(1.7–2.0) qattiq-suyuqlik nisbati, 25°C harorat va 60 daqiqa davomida qayta ishlash sharoitida yuz beradi. Ushbu shartlarda hosil bo‘lgan К2SO4•(NH4)2SO4 qo‘sh tuzi yuqori sifatga ega bo‘lib, К2O miqdori 50.90–51.20% gacha yetadi va iflosliklar darajasi minimal bo‘ladi. Olingan natijalar foydali qazilmalarni qayta ishlash sohasida ekologik xavfsiz va barqaror texnologiyalarni sanoatga joriy etish uchun muhim amaliy ahamiyatga ega
