Main Difference – Bauxite vs Iron Ore. An ore is a naturally occurring solid material from which a metal or valuable mineral can be extracted profitably. An ore is a type of rock. Ores are extracted from earth via mining and then are refined to obtain important metals and minerals. Different types of ores have different elements.

Yes, it is possible to extract iron from sand or from some rocks. To do so you have two really good options. You can use Black Sand or Iron Ore. First, let's concentrate on sand. Typically dark grey or blackish sand will have higher iron content than whiter sand. Dark brown sand doesn't mean there will be more iron than white sand.

Composition: Iron ore is primarily composed of iron, usually in the form of iron oxides such as hematite (Fe2O3), magnetite (Fe3O4), or goethite (FeO(OH)). It may also contain other elements or minerals as impurities, such as silica, alumina, phosphorus, sulfur, and trace elements.; Physical properties: Iron ore is usually hard, dense, and …
