Metal Profile: Iron Properties and Characteristics
History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores. The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 …

Different Types of Iron Ore
Titanium is objected to by users of iron ores, because it is said to make a pasty slag and to interfere in other ways with the smooth running of the blast furnace. At present, ores containing more than 5% or 6% of titanic acid (TiO2) are not saleable. ... Magnetite is easily spotted by its weight, hardness, black powder, and attraction for the ...

The hardness values of the minerals that make up the iron ore found in the literature are presented in Table 1. Mohs hardness is a measure widely applied to minerals and presents relative hardness values [15]. Microindentation is also a commonly used technique and can be performed with a Vickers [16] or Knoop indenter [17].
