As a base case, we assume that taconite ore is being blasted with a heavy ANFO (HANFO) having absolute weight strength of 3.35 MJ/Kg (801 cal/gm). The 80% passing size of the blasted ore has been measured and found to be 40 cm (15.75 inches). The ore passes through primary and secondary crushing and grinding.

The ore feeding this crusher was unusually soft for taconite ore, resulting in emissions that were approximately one percent of normal crushing operations. Thus, it is reasonable to suspect that the composition of the this ore may have been significantly different from most other taconite ores. In addition, the report presents only ...

The objective of this project was to develop noise control designs for secondary crushers in taconite plants. The project included reducing the noise levels of the secondary crusher at the Jackson County Iron Company, such that the levels at 1 meter from the basic unit and 1 1/2 meters above the floor are 85 decibels, a-weighted network (dba).

TACONITE MINING Taconite mining and processing is very costly due to the hardness and abrasiveness of these low grade iron ores. The processing usually involves two stages of crushing and coarse and fine grinding after primary crushing, and the comminution costs per tonne will increase substantially for each downstream stage.
