The transition metals form similar compounds [such as FeCl 3, HgI 2, or Cd(OH) 2], but they are more likely than main group metals to form complexes, such as the FeCl 4-, HgI 4 2-, and Cd(OH) 4 2-ions, that have an excess number of negative ions.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and ...

regards grindability, HGI (Hardgrove grindability index) and BWI (bond work index) are the most employed tests. Although many processes require pulverized limestone as raw material, neither HGI nor BWI has been taken into con-sideration along with the mechanical parameters for lime-stones in specific. On the other hand, many studies

Compared to La Loma (HGI of 46), all biomasses tested performed poorly with low HGI values (14–29). Miscanthus pellets had the highest BWI or Wi at 426 kW h/t. Despite similar HGI values, some untreated biomasses showed lower BWI values (Eucalyptus pellets Wi 87 kW h/t, HGI 22) compared to others (sunflower pellets Wi 366 kW h/t, HGI 20).

The comparison between all putative reaction channels confirms that two-body dissociation is the dominant dissociation pathway. After this primary bond breakage, two parallel channels proceed. Transient HgI associates nongeminately with an iodine atom to form HgI 2, and I 2 is formed by nongeminate association of two iodine atoms.
