    Bioleaching of Sulfide Ores by a Pure Culture of Acidithiobacillus Thiooxidans
    (GMIT, 2022) Anand Oyunbat; T. Hollenberg; Munkhzaya; Ariuntuya
    Throughout the world, the reserves of metal ore deposits are dwindling, research into the extraction of metals from low grade deposits are becoming increasingly important. Low concentrations of Cu, Fe were analyzed in the Oyu Tolgoi Southwest deposit’s Phase 4B ore, which is unsuitable to be extracted through flotation method. Bacterial cells have been shown to be capable of converting metals form solid to liquid phase in the bioleaching process.

    Determination of heavy metal concentration of surface water in Nalaikh area and the study of its reduction methods
    (GMIT, 2022) Anuujin Bayansan; Ariuntuya; Sarangerel
    This study aims to assess heavy metal pollution in surface water in Nalaikh, Mongolia. Sampling locations are taken from Bus Lake, polishing pond in Gorod WWTP, runoff,and shallow lagoon. Bus lake was used for traditional treatment and some types of birds such as gulls etc inhabit and drink. The runoff and shallow lagoon were only taken for observing the content of arsenic and chromium.

    Study of wastewater treatment based on the DAF for the small-scaled industry
    (GMIT, 2020) Nandin-Erdene Munkhbat; Ariuntuya; Daniel Karthe
    Most of the Mongolia industry scale is small sized industry comparing other country. Therefore, there is an important need of small scale pre-treatment plant of industrial wastewater in Mongolia. As nowadays requirement for protecting environment, all small scale industry have to install WWTP before discharge the wastewater into environment and sewerage network. The wastewater treatment plant at a poultry slaughterhouse comprises a dissolved air flotation (DAF) system. The DAF system at small-scale industries especially poultry wastewater treatment is designed to remove high concentration of organic pollution such as FOG, BOD, COD and TSS. Formulated on the literature, the DAF operation of the system removal efficiency at 300kPa pressure, PAC coagulation and anionic polymer is shown optimal result
