1 Introduction Iron ore pellets are one of the significant sources of iron for iron and steel making due to their superior metallurgical performance low energy consumption and less emission of environmentally harmful dust and gases during the production process [1] [2] [3] The two primary raw materials for pellet production are hematite and magnetite concentrates
Fig 4 shows the process stages of a possible iron ore beneficiation for magnetite ores or also siderite and taconite ores that have only a low to medium iron content After comminution and screen sizing the coarse ore and fine ore streams are treated separately The coarse ore stream is fed to a DMS trommel and then wet screen classification
Processing of Magnetite Iron Ores Comparing Grinding Options B McNab1 A Jankovic2 D David3 and P Payne4 ABSTRACT Although the majority of current steel production is supported by iron ore sourced from high0grade haemetite deposits the long term growing demand for steel has led to higher raw material prices and opened the way

It is easy to understand that the increase in the magnetic induction increases the magnetic capture force on magnetite particles in the separation process thus improving the concentrate yield and the magnetite iron recovery of concentrate Processing of Magnetite iron Ores Comparing Grinding Options Australasian Institute of Mining and
Processing of Magnetite Iron Ores Comparing Grinding Options Article Full text available Jan 2009; B Mcnab; There is a rich and long history of magnetite ore processing in Western
ABSTRACT Information obtained from comminution test work at the laboratory scale can be utilized to characterize ore types and predict their behavior during comminution at the industrial scale Comminution tests with a laboratory scale rod and ball mill of 13 predefined ore types from the Per Geijer iron oxide apatite deposits were conducted The grinding setup
Analysis of the current technical solutions for the processing of iron ores showed that the high grade ores are directly exposed to metallurgical processing; by comparison low grade ores depending on the mineralogical and material composition are directed to beneficiation including gravitational magnetic and flotation processes or their combination
