The development stage readiness: Introduced in production

Description of the development:
()
Processing technology provides that a solid mass of sludge after grinding, alkali removal and washing with water, wring out and sent to the acid leaching to produce calcium nitrate enriched in trace elements, which is used as fertilizer The alkaline solution is acidified with an acid solution of a falling zinc hydroxide, which is processed into zinc sulphate. Recrystallization of zinc sulfate is carried out by adding a stock solution of the oxide reagent. At the stage of acid leaching is applied as a foam skimmer and insoluble precipitate. Skimmer combined with power to neutralize the gases produced in the process of acid leaching
