which the highest iron of hematite magnetite siderite

which ore has the highest iron content hematite magnetite . 2013-04-10 Iron ore – Wikipedia, the free encyclopedia. Ores carrying very high quantities of hematite or magnetite (greater than ~60% Banded iron formations may contain iron in carbonates (siderite or ankerite) or and process as they require less beneficiation due to the higher iron content.
