  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.
