EXTRACTION OF A HIGH PURITY OF ZINC COMPOUNDS FROM GALVANIZING DROSS FOR MEDICAL APPLICATIONS

Abstract

This work include extraction a high purity of Zinc compounds such as Zinc Sulphate «99.9%», Zinc Chloride «99.57%» and Zinc Oxide «99.87%», which suitable for medical applications from industrial solid scraps always form upon galvanizing on the surfaces of the Zinc molten tanks as a dross normally contain a percentage of impurities mainly Zinc Oxide «87%», also the research includes describe for the metallic apparatus which used for extraction a high purity Zinc compounds by using thermal and wet methods, and the value of X-ray diffraction and all chemical analysis where described and well established.
