  • Leaching of zinc from low grade oxide ore using organic acid

    Abstract: The leaching of low grade zinc oxide mining tailings by organic acid as a leaching agent was investigated. Zinc was extracted successfully from sample by citric acid leaching. The effects of solid to liquid ratio, acid concentration, reaction time, temperature and ore particle size on the leaching efficiency.
