Vale's ore projects prioritize iron rather than silica reduction

摘要

Vale's top iron ore executive on Thursday acknowledged the silica content in its products is rising, and that it may remain an unattractive feature longer term, even as the proportion of iron in its ores is boosted by new concentrators and resources. New plants such as the Itabiritos projects will help boost the iron content rather than greatly reducing Vale's silica content for its overall iron ore shipments, Jose Carlos Martins, Vale's ferrous minerals and strategy director, said in translated remarks at a company briefing in London.
