Mineral and grain development should provide granular textures with well defined sharp grain boundaries to facilitate liberation and separation of metallic minerals... These features are usually achieved in highly metamorphosed iron-formation where there is optimum grain enlargement, and magnetite facies are usually preferred over hematite or mixed facies crude ore.  1, record 2, English, - magnetite%20facies

Oxide facies... is the most important facies. It can be divided into the hematite and magnetite subfacies according to which iron oxide is dominant. There is a complete gradation between the two subfacies.... Oxide facies BIF [banded iron formation] typically averages 30-35% Fe. These rocks are mineable provided they are amenable to beneficiation by magnetic or gravity separation of the iron minerals.  3, record 3, English, - oxide%20facies

Well segregated oxide facies containing 30% or more iron in discrete grains or grain clusters of hematite, magnetite and goethite uniformly distributed in a cherty or granular quartz matrix are most suitable for ore. Oxide facies are selected that are clearly segregated from silicate, carbonate or sulphide facies and other barren rock...  4, record 3, English, - oxide%20facies

Red ore is composed of earthy red hematite, goethite, soft aluminous silicates, and very fine grained chert or quartz. It is derived from the upper iron-rich part of the Ruth slate at the base of the iron-formation and from black slaty facies within it.  1, record 4, English, - red%20ore
