Bond Work Index - an overview | ScienceDirect Topics
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 ...

Processing of Nickel Laterite Ores on the Rise
The SX-EW Method. SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step.
