The characteristics of dump zinc-containing sludges from chemical enterprises producing artificial fibers are given. The analysis of quantitative, chemical and phase compositions of sludge fields is carried out. The possibility of pyro- and gyrometallurgical processing of these materials was established. The need for preliminary preparation of sludge for processing is shown. Technological recommendations for obtaining marketable sulfate and zinc oxide are formulated.
