The conferences have now become an important biennial bringing together geologists, geoscientists, mineralogists, metallurgists, managers, engineers, operators, equipment manufacturers and service providers from across the iron ore industry. This volume contains 80 papers, covering topics such as agglomeration, beneficiation, exploration and geology, ferrous burden performance, materials handling, mining, new equipment and environment, ore characterisation and geometallurgy, and project development. 606 $aAgglomeration 606 $aGeology 615 0$aAgglomeration. 615 0$aGeology. 712 02$aAustralasian Institute of Mining and Metallurgy. 906 $aBOOK 912 $a9911006860803321 996 $aIron Ore Conference 2015$94387687 997 $aUNINA LEADER 03726nam 2200613Ia 450 001 9910967713203321 005 20251116181548.0 010 $a1-60876-297-1 035 $a(CKB)2550000001041266 035 $a(EBL)3018309 035 $a(SSID)ssj0000835057 035 $a(PQKBManifestationID)11519943 035 $a(PQKBTitleCode)TC0000835057 035 $a(PQKBWorkID)10989634 035 $a(PQKB)10553717 035 $a(MiAaPQ)EBC3018309 035 $a(Au-PeEL)EBL3018309 035 $a(CaPaEBR)ebr10660170 035 $a(OCoLC)847643476 035 $a(BIP)18780750 035 $a(EXLCZ)992550000001041266 100 $a20080318d2008 uy 0 101 0 $aeng 135 $aur|n|---||||| 181 $ctxt 182 $cc 183 $acr 200 00$aCFD modeling and optimization of fuel-cell systems /$fP.L.
