  • Selection of interhole and interrow timing for surface

    Delay timing is an important and critical blast design parameter which may have a direct impact on frag mentation, muckpile characteristics, backbreak and ground vibrations (Lang 1979, Anderson et al 1985; Chiappetta 1997,1998; Cunningham 2000) As discussed by Jimeno et al (1995), delays should permit the succession of the following events: Propagation of the compression and tensile Iron Ore Fume Risk Reduction Fume Risk Reduction The generation of nitrogen oxides within postblast gases (commonly referred to as “fume”) has become increasingly important for mines from a safety, productivity and regulatory standpoint, particularly those in populated areas In response to industry demand, Orica has developed a complete Fume Risk Reduction protocol that takes a Iron Ore OricaExample: A new iron ore deposit is to be worked by surface mining methods with 15 m benches using 150 mm diameter blastholes Since the prevailing condition is dry rock, it has been decided to use bulk ANFO with emulsion cartridges as primerH BLASTING IN SURFACE EXCAVATION

  • Blast furnace Wikipedia

    Blast furnaces operate on the principle of chemical reduction whereby carbon monoxide, having a stronger affinity for the oxygen in iron ore than iron does, reduces the iron to its elemental form Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and The iron, obtained from blast furnace is called pig iron It contains about 95% iron and 5% carbon and other impurities Previous Year Papers Download Solved Question Papers Free for Offline Practice and view Solutions Online Test Series Take Zigya Full and Sectional Test Series Time it out for real assessment and get your results instantly Test Yourself Practice and master your The iron, obtained from blast furnace is : from Chemistry customers of iron ore mines want a specific size range for hematite entering their processes and it has been known that these customers are prepared to pay a 20%premium for ‘lump’ product This premium can be achieved with minimal additional costs of production for the iron ore Controlling fragmentation Orica Mining Services
