Introduction

• Introduction
• "Evaluating the years we spent in the past," who was yesterday, who are we today? " Based on the question, we have a deeper understanding of their nature and meaning.
• At the same time, we need to think about the question “who will we be tomorrow and what new goals we will achieve”, and not only think about it, but also answer it with our practical work” Islam Karimov.
• Currently, the products of the ferrous and non-ferrous metallurgy of the chemical industry plays an important role in the development of engineering, electronics, automotive, aircraft, oil and gas, light industry and others.
• Sulfide zinc concentrate is fed to the firing, often after enrichment with particle size <0.076 mm and therefore cannot be milled. It is necessary to average the charge before firing. At zinc plants, averaging is carried out by layer-by-layer blending of various concentrates and circulating materials on concrete sites and their subsequent mixing using clamshell cranes. In some cases, magnetic separation is included in the zinc concentrate preparation scheme to remove metal objects from them.
