  • Characterising the Blasting Properties of Iron Ore

    Most iron ores occur in mine benches as complex mixtures of lithologies and ore types. This significantly complicates their characterisation for both blast design and fragmentation modelling. A great deal of technical and research effort has been applied to the development of models to predict fragmentation from rock blasting. A number of quite useful engineering models are currently availableRecently developed blasting techniques in frozen iron ore,2008-3-7 · Iron Ore Company of Canada,.Schefferville, Qukbec, Canada COG 2TO Based on a research program carried out by the Iron Ore Company of Canada in the Schefferville area since 1970, considerable improvements have been made related to the blasting of frozen ore and waste material.
