Authors: Lavinia Lupa, Petru Negrea, Aurel Iovi, Mihaela Ciopec, Giannin Mosoarca


Abstract:

Zinc is the 27th most common element in the earth’s crust. More importantly, zinc is fully recyclable. Zinc can be recycled indefinitely, without loss of its physical or chemical properties. In this paper was made studies regarding the recover of zinc from zinc ash resulted during thermal zinc coating by extraction with clorhidric acid solutions in the view of the zinc chloride solution obtaining which can be used at the obtaining of the flux solutions.


Keywords: zinc, extraction, ash, clorhidric acid
