The most widely used parameter for measuring the hardness and grindability of any ore (rock material) is its work index. The work index of an ore is its comminution parameter, expressed as the resistance of the ore to crushing and grinding and is numerically equal to the kilowatt hour per short tonne (KWHT) required to reduce the ore material ...

Grindability of granite and Iron-ore was investigated in this work. Samples were collected from Julius Berger Quarry and National Iron-Ore Mining Company (NIOMCO), Itakpe. Particle size distribution of the samples by means of sieve shaker and
A decrease in grindability is evident in most cases when comparing the untreated ore work indices to the work indices obtained from unreduced ore at 450° C for the three grindability levels. This phenomenon is thought to be caused by the stress relaxation and annealing of cracks originally present in the feed material.
The influence of reduction roasting and thermal shock on the grindability of a refractory low-grade Michigan iron ore was examined in bench-scale tests. The quantitative effects of the various treatments were evaluated at three sieve levels, 48, 100, and 400 mesh, with ball-mill-grindability and work-index parameters as response indicators.
The bond work index is a measure of ore resistance to crushing and grinding and is determined using the bond grindability test its value constitutes ore a new approach to bond grindability and work index 32 bond grindability test the samples from which sonic velocity measurements are taken are crushed in a laboratory scale jaw crusher.

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 ...
And thus, the grindability of the iron ores was investigated. The results obtained are as follows: (1) The work indices of the iron ores are ranged from 6.22 to 17.40. The work indices of the Santa Barbara ore, the Santa Fe ore and the Chile ore are greater than 17 and these ores are remarkably hard.
