  • Iron ore extraction techniques - ScienceDirect

     · was won by drilling and blasting .As mining technology generally developed, so did drilling techniques and the explosives used. Smith 1990 reported that the Cleveland deposit was associated with a very strong stone roof rock known as “dogger” allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this

  • PDF Optimization of iron ore blending in the COREX shaft

    matching principles were proposed and five optimized schemes designed and verified by laboratory experiments to prove the effectiveness of the improved evaluation method

  • Investigation and technological optimisation of iron ore

    The bedding and ores has been investigated by means of laboratory trials, industrial sampling and a mathematical model. It has been revealed in the present work that an increase in the total number of ingredients participating in the proportioning procedure would greatly improve the quality of the base mix

     · Perhaps the best illustration of this slow progress has been the history of the process, promoted by its proprietor as “the world’s first commercial direct smelting process for making iron straight from the ore” Rio Tinto, 2014. Its history goes back to the development of bottom-blown oxygen converters and combined steelmaking by Klöckner Werke in the early 1970s

  • ore bedding and blending process - Simone Pachur

    The entire process is called the blending operation in iron ore handling Bed blending theory was firstly discussed by Gerstel in 1977 Gerstel 1977 Not far from that Gy presented a new bed blending theory to suppress the continuous input variations for a steady output quality grade Gy 1981 Several crucial assumptions were made to
