The average grade of the circular haulage road was 10%. - There has been a total of 70 million tons of waste rock removed from the pit to date...and at the time, 2 ~ 250 HP pumps were needed to pump excess water from the pit for excavations to continue. - The breakup of the rock and ore was accomplished with sets of drilling patterns boring 7 inch holes 60 feet into the bedrock, and filled with 8 - 32, 000 lbs of explosive. Each blast could yield 20 - 80,000 tons of rock and ore. - Electric shovels used - 3 with 6 cu. yd. dipper, 1 with an 11 cu. yd. dipper....Dumptrucks used - 6 ~ 105 ton with 1000 HP diesel electric drive, 2 ~ 55 ton with 635 HP diesel engines. - Total mine production: 1.3 million tons of iron ore / 3.5 million tons of waste rock. - Process: The iron ore containing magnetite is crushed and ground, magnetically separated to produce 65% iron concentrate, then converted by roasting into hematite pellets ( 3 crushers of 350 HP each, 2 rod mill grinders of 350 HP each and 2 ball mills). - The 2400 degree F. roasting took place in 4 vertical shaft furnaces 6 X 12 feet and 40 feet high. - Annual plant production: 520,000 tons of hematite. - A daily ore train of 30 to 35 cars took pellets south to Picton port for loading into the 25,000 ton ore boats.  Media Coverage  Future Plans  Stories Add your own story  Photo Galleries 02.27.05 Tue, Mar 22nd, 2005 posted by manitou 24 pictures honey is yum Mon, Jul 18th, 2005 posted by nightbird 4 pictures Peterborough Meet Sat, Oct 27th, 2007 posted by phrenzee 16 pictures ...into the belly of the beast Tue, Oct 30th, 2007 posted by bandi 9 pictures Get out now!
