Steel wear calculation. The Bond Abrasion Index is a measure of how readily a rock sample will wear away steel that comes into contact with it. It is conventionally used to estimate the liner and media wear rate in rod mills, ball mills and crushers. This is a batch test and returns a result in units of grams (the amount of metal that wears off ...

In the iron ore concentrate pelletizing industry, the Abrasion Index (AI) is used to indicate the abrasion resistances of pellets. The Abrasion Index (AI) is defined as the quantity of "fines" (material finer than 0.5 mm by ISO 3271:2007 or 0.6 mm by ASTM E27997) - produced while pellets tumble in a rotating drum.
Metal Bulletin Iron Ore Index (MBIOI) Guide Methodology, Specifications and Usage This guide is intended to introduce users to the market-leading Iron Ore Indices provided by Metal Bulletin. Metal Bulletin have been reporting iron ore transactions since 1913 and were instrumental in the development of the annual benchmark system.
iron that occur in more than one valence state. For minerals that contain iron, the ferric/ferrous ratios may be estimated from microprobe analyses by normalizing according to a total number of cation per formula. For example, if there are no cation vacancies in a clinopyroxene, there will be a total of four cations per formula.
The ore is characterised for impact breakage by two parameters: A and b. The value of the multiplication of these parameters, the A*b value, has been found to have the best correlation with ore resistance to impact breakage. Lower values indicate harder ores. The table below shows typical ranges. Low energy (abrasion) breakage is
