  Description of the technological process.

•   Preparation of solutions and dehydration.
• Technical zinc sulfate is produced by evaporating a solution of zinc sulfate in a fluidized bed furnace (BL).
• The solution after cementitious purifications from cadmium in the cadmium production is fed to the filter press for filtering. The filtered solution is sent to a filler with a capacity of 70 m3. From the collection container, the gravity solution is periodically poured periodically as necessary into a 20 m3 supply tank. The tank is equipped with a level gauge for measuring the amount of solution. From the supply tank, the olution is pumped to the nozzles and sprayed into the furnace.
