    parameters for cyanidation on sulfidic gold rich ore from Olon-Ovoot mine
    (2018) Enerel Lkhagvadorj
    The purpose of the research is to optimize parameters for cyanidation on sulfidic gold rich ore from Olon-Ovoot mine. Characteristic of ore has changed due to depth displacement. Therefore processing plant parameters had to be updated. Ore samples were grinded to 65%, 75% and 80% of -74μ and leached in 200ppm and 250ppm sodium cyanide solution which are the most suitable concentration range for sulfidic ore. As a result of the experiment, leaching 80% of -74μ ore in 250ppm NaCN solution for 32 hours was the optimal parameters for highest gold recovery which is 92.1%.
