2019-9-23 Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.

2018-10-1 As the iron ore grade declines, the rate of increase in GHG emissions from mining accelerates. For example, when iron ore grade decreases from 40% to 35%, the average GHG emissions for mining increases by 12 kg CO 2 e/tonne. In contrast, the same 5% iron ore grade decrease from 20% to 15% would lead to 52 kg CO 2 e/tonne. Thus, China will face accelerating energy consumption and increased GHG emissions for every tonne of iron ore extracted and processed

Abstract. The demand for iron ore has been increasing in the recent years, thereby requiring the adoption of fast and accurate approaches to iron ore exploration and its grade-assessment. It is in this context that hyperspectral sensing is deemed as a potential tool. This paper examines the potential of hyperspectral fingerprints in the visible, NIR and SWIR regions of the EMR to assess the ...

In order to develop downstream processing routines for iron ore and to understand the behaviour of the ore during such processing, extensive mineralogical characterisation is required. To determine mineral associations, mineral liberation and grain size distribution, imaging techniques have to be used. There are two main imaging techniques used for the characterisation of iron ore, ie, Optical ...
