Answer (1 of 2): Naturallyoccuring iron ore varies in it's content. Also, you haven't said whether it is "benefacted ore" (crushed, with gangue material removed), or straight out of the ground. Obviously, if the latter is the case, even very rich ores seldom contain better than a few percent of ...
Break it Better
Sep 01, 2011 · Break it Better – Mine Blast Fragmentation. Jack Eloranta of Eloranta Associates stresses the importance of timing a blast properly. "It may take days or weeks to drill out a pattern and loading might take hours or days. But, the time span that really matters is the interval from the detonation of one hole to the time the adjacent hole fires.

At blast pattern level, faults and folds at the 120 meter scale tend to follow the trends seen in the larger structures. These features, while of relatively small amplitudes, can be significant in the detail block modeling and ore type boundaries.
Drilling, Charging and Blasting Productivity
Reduce drill and blast costs. Advanced blasting technology and clever blast design can improve the utilisation of the drilling fleet and reduce capital and operating costs without compromising productivity. Matching explosive energy to geology enables expanded patterns without affecting fragmentation.
