Leaching of zinc from low grade oxide ore using organic acidoxide ores have been considered. The leaching of low grade ore is attracted considerably in recent years. One of the most important sources of low grade ores in zinc mineral processing is zinc mining tailings. Smithsonite (ZnCO3), hydrozincite. (2ZnCO3·3Zn(OH)2), zincite (ZnO), willemite (ZnSiO4), gahnite (ZnAl2O4),.smithsonite mining process,Flotation of zinc oxide ore using cationic and cationic-anionic mised .Department of Mining and Metallurgical Eng., Amirkabir University of Technology, Tehran, Iran.
