Process
The  mined   ore   is   transported   from benches  to  three   Gyratory   Crushers capable  of crushing the ore to minus 7" size. The  crushed  ore is screened into coarse  and fine fractions before feeding to  Autogenous Mills. The ore ground to minus  20  mesh  size  is  subjected  to primary  magnetic  separation  and   the concentrate,     after     re grinding,     is subjected    to    secondary    magnetic separation. Column  floatation   system has  also  been incorporated to improve the  quality  of   magnetic   concentrate.

The  primary  magnetic   tailings   are subjected   to   spiral   separation   to recover   non - magnetic   concentrate which  is  also  further ground  in the Ball Mills. Flotation technique for improvement in the quality of iron ore concentrate has also been added to the production facilities in the mining and beneficiation plant. Process   modifications are carried out regularly to ensure that the product quality conforms to the product specifications in line with the requirement of the market.


The  concentrate  produced  is  pumped  through a 67 Km long slurry pipeline to Mangalore where  the  slurry  is  filtered to produce filter cake with about 9% moisture. The tailings are pumped to a tailings dam from a different location in the same dam and clean process water moves  by  gravity  to   the   concentrator   plant. The   entire   operation   using  the   most sophisticated  equipment  from  crushing  to  ship  loading is fully automated and computer controlled. Computerized  mine  planning  techniques  are in use to  maintain strict quality control and process parameters.>
