The existing screening plant (SP-I) at Donimalai processes around 7 MTPA of iron ore produced from DIOM. In order to process iron ore from both DIOM and KIOM, NMDC proposes to install a second Screening and Beneficiation plant–II (SP-II) of 7 MTPA capacity. The SP-II project is proposed to be consisted of four (4) screening lines (three (3)
