Abstract

Galvanizing plant waste (zinc dross) containing 27.66% zinc was leached in HCl solutions. Zinc in solution was precipitated as Zn(OH)2 by adding ammonium hydroxide. The product was characterized by atomic absorption spectroscopy, thermogravimetric analysis, x-ray diffraction analysis, and scanning electron microscopy. X-ray diffraction analysis confirmed that when heated at 500oC, the product possesses hexagonal zincite structure. Scanning electron microscopy confirmed that the shape of zinc oxide particles was spherical and compares well with the standard product. A maximum of 93.7% zinc contained in the dross could be extracted and converted to zinc oxide having a purity of 98.8%.
