Iron ore - Wikipedia

Prehistoric societies used laterite as a source of iron ore. Historically, much of the iron ore utilized by industrialized societies has been mined from predominantly hematite deposits with grades of around 70% Fe. These deposits are commonly referred to as "direct shipping ores" or "natural ores". Increasing iron ore demand,.

Energy Use of Fine Grinding in Mineral Processing | SpringerLink

Dec 18, 2013 . This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media use are strongly related to stress intensity, as well as.

Types of Iron Ore: Hematite vs. Magnetite | Investing News Network

Jun 14, 2017 . While magnetite ore requires more treatment than hematite ore, end products made from magnetite ore are typically of higher quality than those produced from hematite ore. That's because magnetite ore has fewer impurities than hematite more; in this way, the elevated cost of processing magnetite ore can.

Iron Ore and Pellets - Vale

But, before this, the ore goes through a blast furnace that only works when air can circulate freely. For this reason, the material needs to be big enough so that there are spaces between each piece. On top of this, the ore needs to be strong enough not to be crushed thereby obstructing the blast furnace. Thus, the production.
