بررسي جنبه هاي اصلي و موثر در آبشويه ميكروبي كانسار ايلمنيت (FeTiO3) توسط سويه بومي Thiobacillus ferrooxidans

Survey important features of ilmenite ore (FeTi03) bioleaching with native Thiobacillus ferrooxidans strain

With study of biologic iron cycle suitable candidates was selected to Ilmenite bioleaching. Finally Thiobacillus ferrooxidans isolated from weakest water of Talesh chooka factory and suitable media to its isolation and purification the best selective broth medium was suggested medium DSMZ with pH= 1.4 and inorganic medium was 2:2. We used concentrated ilmenite with 47% of purity Caspian Sea beach sample with 7% of purity and isolated microbial strain from weakest water of Talesh chooka factory in leaching study. In this project, used Agitation technique and content ilmenire was 10% of leaching medium there is studied several factors. In bacterial leaching of ilmenire by isolated microorganism, ilmenite leaching process depends on some factors such as pH, temperature, number of microorganism, size, kind of ore, quantities of Fe+3.
