    Abstract:

    This study focuses on hydrometallurgical treatment of lateritic nickel ores obtained from Manisa - Caldag region of Turkey. 1.58 % of nickel and 0.12 % of Co containing lateritic ores characterized by both chemical analysis and x-ray diffraction. Leaching conditions of ore were carried out by determining the optimum parameters such as sulphuric acid concentration, leaching duration, stirring rate and solid / liquid ratio. Nickel and cobalt were extracted in the form of nickel sulphate and cobalt sulphate solutions after the leaching, respectively. The dissolution of iron in the ore during the leaching process was monitored. Finally several hydrometallurgical purification techniques were carried out to obtain relatively pure nickel and cobalt solution for further reduction / refining techniques.
