Processing of wastes of sludge field of Tajik Aluminum Company

The technological parameters of aqueous treatment of waste of sludge fields of Tajik Aluminum Company have been studied; technological regimes of the processes have been defined: washing temperature 25-40 Deg C, mass ratio of sludge and water - 1:5, duration of the aqueous treatment process - 30 minutes. Under these conditions, the degree of extraction of water-soluble components of the waste reaches 95% and above, and the optimal parameters for the decomposition of solid residue with sulfuric acid after aqueous treatment of the sinter to obtain useful components have been established.
