Agree, a simple gravity process. Benefication should cost about USD30/tonne (final 66% fe tonne). Process already used in brazil by VALE (formally CVRD)even long before the IO price increases. Produces a product suited for sintering or pelletising.
The capital cost of building the benefication plant could be more than 1 Billion Dollars, hence why SDL what to mine DSO for the first seven years to save on raising capital.
