Iron Ore Statistics and Information - USGS

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries.

Background - ioresearchhub.newcastle.edu.au

Iron Ore Beneficiation Beneficiation is concerned with recovering and concentrating the valuable ore from the run-of-mine feed, with different technologies applied to specific particle size ranges. Fine particles are usually well liberated, and thus have the potential to produce high grade concentrate.

In addition, Buena Vista also provides a very favourable ore characteristic given its intrusive origin. In this regard, the magnetite at Buena Vista is much coarser grained, and softer, than typical banded iron (BIF) hosted magnetite deposits and consequently much more easily liberated during the beneficiation process.
