Developing proxies for routine measurement of ore hardness: A mineral sands case study
… ore during comminution is directly linked to its hardness. Thus, understanding ore hardness variability is paramount to effective mining and processing. Traditionally, ore hardness is measured using single particle breakage tests, such as the JK drop weight test. However, direct hardness testing …

Nanoindentation of Gold Single Crystals
… spectrum of residual deformation, with measured hardness values on the same surface differing by over a factor of two. The yield point also exhibited considerable variation, but the depth of penetration was independent of this elastic–plastic transition. The onset of plastic deformation in these …
