Sintering is the most extensively used and economic agglomeration process to prepare iron ore fines for blast furnace use. Granulation is the most critical factor controlling iron ore sintering process, as it improves sinter mix permeability. Currently, sinter plants are receiving significant proportion (up to 40%) of − 150 μm micro-fines in …
Characterization and beneficiation of dry iron ore processing plant reject fines of Khondbond region, India, was investigated. Different characterization techniques viz. size analysis, size-wise chemical and density analysis, X-ray diffraction analysis, sink-float analysis, thermo gravimetric analysis, scanning electron microscopy, and …
Currently, the beneficiation plant produces a magnetite concentrate that is agglomerated in three older sinter plants, which are no longer capable of fulfilling the product quality requirements and environmental regulations.
China Iron ore beneficiation line click for more details :details Due to the strong magnetic properties of the ore and good grinding, the domestic magnetic separation plant adopts stage grinding ...
This article aims to describe the partitioning of trace elements between the products (sinter) and plant emissions in an iron ore sinter plant, aiming to better understand the behavior of these elements in the sintering process to eventually support interventions to modify these partitions.
