Analysts believe Fortescue's iron ore will be less vulnerable to price discounts in future, as the company studies an option to use the magnetite concentrate from its $US2.6 billion Iron Bridge project to blend with its traditional iron ore products.

Price pressure on Fortescue's products, which contain less iron than those exported by Rio Tinto and BHP, peaked in fiscal 2018 when the company received just 64 per cent of the ''benchmark'' iron ore price.
