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].
