Iron Ore can look like many things depending on what grade the ore is if it is a high grade such as Hematite (70.0%) or Magnetite (72.4%) then the ore will have a silver gray type but if the ore has a lower iron content like Goethite (62.9%) or Siderite (48.3%) then it is more likely to look like the type of rock that it was mined from.

Magnetite is a raw material used for Advanced Fabrication. It is one of the more difficult materials to locate. It can be found in Ore Veins and Spy Pengling crevices in the Arctic Spires and Glacial Basin areas, in the Deep Lilypads Cave on the wall and ceilings (though only a few spawn here), and on the floor of the Crystal Caves. It can also be provided by …

The particle size of the raw magnetite ore is in the range of 125–500 μm, which is achieved by mixing 50 wt.% of 125–250 μm and 50 wt.% of 250–500 μm. For the oxidation treatment, 1000 g of the raw magnetite ore was charged into a steel vessel and put into a conventional heat treatment furnace at 800, 900, and 1000 °C for a specific time.
