Özet

Organic acids have been used as leach reagent in hydrometallurgical processing of some ores in recent years. In this study, the usability of the solutions containing acetic acid and ammonium acetate for the leaching of malachite ore was investigated. The effects of acetic acid/ammonium acetate ratio, temperature, solid to liquid ratio, and particle size on the leaching rate of malachite ore were examined. It was determined that the leaching efficiency was higher in case of high acid and low salt concentrations. It was determined that almost all copper in malachite ore was passed into solution medium. The kinetic analysis of the leaching process was done, and it was found that it followed the diffusion model through the product layer.
