one is Bond's grindability test which has been a widely accepted approach, and the second one is Hardgrove's index generally used for coal (Stamboliadis et al., 2011; Gamal, 2012). The Bond work index is regarded as size reduction resistance. It can therefore be presumed that the BWI is correlated to the physical and mechanical

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
