2018年10月1日· In the present study, the leaching behavior of the solid wastes from two iron ore mines, one in India (Asia) and another in Liberia (West Africa) was investigatedLeaching is carried out by two main methods: simple leaching at ambient temperature and atmospheric pressure; and pressure leaching, in which pressure and temperature are increased Metallurgy Leaching,Metallurgy Leaching, Extraction, Deposition,
Iron ore mines generate a large volume of wastes – overburdens, tailings, etc, that contain a sizable amount of harmful trace elements viz Pb, Cu, Se, Mn, Cr, Hg, As, Ni, Cd, Zn,(Martino et al , 2004) One possible way to obtain iron from low grade ores is through the microbial leaching This study was aimed at isolating the iron solubilising fungi forFUNGAL LEACHING OF IRON ORE: ISOLATION,
