Nitride leaching of copper-zinc sulfide middlings that are difficult to concentrate is studied with the aim of clarifying and supplementing results obtained previously. It is shown that organization of two-stage countercurrent leaching makes it possible to reduce the concentration of nitrate ions within leaching solution, to increase the degree of nitric acid regeneration, and to increase copper and zinc concentration in solution and precious metals in the residue.
