  • Kami Iron Ore Project, Labrador, Canada Mining Technology

    The mining property lies approximately 6km southwest from the Wabush Mines mining lease. The property includes two contiguous licenses and a mining lease that spans approximately 12km eastwest to 13km northsouth in the National Topographic System (NTS) map of areas 23B/14 and 15. The Kami mine is divided into three zones, namely Rose Central, Rose North and Mills Lake, lying within the highly metamorphosed and deformed metasedimentary sequence of the Grenville Province in the Gagnon Terrane of the Labrador Trough. The Labrador Trough is comprised of a proterozoic sedimentary rock sequence, including iron formation, volcanic rocks and mafic intrusions. Lake Superiortype iron formation, comprising banded sedimentary rocks filled with bands of iron oxides, magnetite and hematite, is found at the deposit. Semimassive bands and dissemination of magnetite and/or specular hematite are contained in the oxide iron formation. The Kami ore body is categorised into three mineralisation typ

    Mining operations will be carried out with an owneroperated fleet, using conventional openpit methods such as drill, blast, load and haul. The mining operations will start with clearing, grubbing and removal of the topsoil. A fleet of shovels and trucks will be used to remove the overburden, which will be hauled to the overburden stockpile. Prestripping overburden removal will be carried out by contractors. Drilling and blasting of ore and waste will be carried out on 14m benches and ore will be loaded into the fleet of haul trucks via hydraulic excavators. The mined ore will either be hauled directly to the primary crusher or stockpiled. Mining operations will proceed on a 24hour basis, seven days a week and 52 weeks a year.

    The Kami processing plant will be located within the Kami Property, to the east of Waldorf Crossing. The run of mine (ROM) will be crushed by a single gyratory crusher located in the vicinity of the Rose deposit. An overland conveyor will carry the crushed ore and discharge it onto an uncovered stockpile near the Kami concentrator. A belt conveyor reclaims the crushed material from the stockpile and feeds the AG mill. Discharge from the AG mill is screened using a twostage screening circuit. Oversize from the scalping and classification screens will recirculate back to the AG mill. The slurry produced from the grinding and screening circuit is subjected to gravity concentration via a threestage spiral circuit to produce tailings stream and the final gravity concentrate. Horizontal pan filters and steam injection methods will be used to dewater the products when required. Cobbing process using lowintensity magnetic separation (LIMS) will be used to concentrate tailings from the

    Chinabased steel company HBIS will purchase 60% of the annual production at Kami, that is up to a maximum of 4.8Mt of the first 8Mt of iron ore, under an offtake agreement. Alderon announced an offtake agreement with a subsidiary of Glencore, in July 2014. Glencore will acquire all of the annual production allocated to Alderon. The iron ore concentrate will be transported by train to the tÎles Port for shipping. A new rail track will connect the mine to the Quebec North Shore and Labrador Railway (QNS&L) mainline that runs to the tÎles ction. An agreement was made in July 2012 with the Port Authority for shipping 8Mt of iron ore annually via the multiuser deepwater dock facility, which is under construction.

    The major works will include the construction of a terminal facility at PointeNoire for ship loading. The facility will be equipped with a new railcar unloading loop track, car rotary dumper and a concentrate storage yard. A new 25km rail track will be built to connect the mine site to the QNS&L mainline. A new road, which will bypass Wabush and connect to the Highway 500, will provide access to the mine. Under security and power purchase agreements, Nalcor Energy will supply the power required for the mine via a 315kV transmission line. Workers will be accommodated at the temporary camp and accommodation facility to the south of Wabush.
