The Bond abrasion index (Ai) is used as a measure of the relative abrasivity of different rock materials on metal and is important to understand for process plant design and operation in crushing, screening, and especially grinding (Bond, 1963). Iron ores are moderate to strongly abrasive with Ai values typically higher than shale and limestone ...

view moreThe Mohs scale of mineral hardness (/ m oʊ z /) is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. Created in 1812 by German geologist and mineralogist Friedrich Mohs, it is one of several definitions of hardness in materials science, some of which are more quantitative.

view moreHardness Hardness determines whether an abrasive particle can etch or provide an anchor pattern on a particular substrate. One way to determine the hardness of an abrasive is to use the Mohs' hardness scale. The scale ranges from 1 to 10, with 1 being the softest (talc) and 10 being the hardest (diamond). Most abrasives that effectively achieve an anchor pattern on a surface have a Mohs ...
