Jul 20, 2016 With the aim of high‐efficiency utilization of carbonate iron ore, a new beneficiation process of preoxidation‐reduction‐magnetic separation is proposed. This work focuses on the oxidation and decomposition behavior of carbonate iron ore during the preoxidation. Based on the single factor experiment and non‐isothermal analysis results.Iron ore is beneficiated using separation steps based on mineral composition without the use of separation steps based entirely on size. In a preferred sequence of steps the iron ore is passed from a ball mill through a magnetic separator where low iron content tailings are rejected and the concentrate passed to a flotation step, where a high iron content concentrate froth is made and the.

The source of the iron in the studied ore sample was in the breakdown of ferromagnesium silicates where iron is present in a ferrous form (Ormo et al., 2004). It was suggested that carbonic acid (resulting from dissolving CO 2 gas in water) weathered the ferromagnesian minerals to form magnesium-iron-carbonate-rich solution.The low-grade clay-rich -1.0 mm fraction of fine iron ores have often proved difficult to upgrade and capital intensive to process when using traditional wet beneficiation technology including single or two stage hydrocyclone desliming, wet high intensity magnetic separation (WHIMS), spirals and final dewatering using fine screens. Very fine ( 0.010 mm) clay-rich slimes simply follow the water.
