Tahlillar natijasi shuni ko’rsatadiki, 10-50 daqiqa vaqt oralig’ida misning eritmadan
cho’kish darajasi 75%, nikelning eritmadan cho’kish darajasi 38% ni tashkil etgan.
Tex
nologik eritma tarkibidagi metallarni choʼktirishda ammoniy rodаnid (NH

CNS, texnologik eritma 100 ml) qo’llab cho’kish
ko’rsatkichlarining kimyoviy tahlili natijalari 3-jadvalda keltirilgan va olingan natijalar
asosida
choʼktirish jarayonining choʼktiruvchi reagent (NH

CNS) miqdoriga bogʼliqlik grafigi
tuzildi (3-4 rasm).
