In this research, the effects of oxygen injection during the induration process were studied in order to improve the quality specifications and increase the rate of production of the iron oxide pellets. Several experiments were carried out in palletizing pilot plant in different conditions of oxygen injection. The results suggested that if only the extra oxygen was injected into the furnace in ...

The use of alternative raw materials is essential for establishing a circular economy in the mineral and ironmaking sectors. Therefore, this study investigates potential lime sludge as fluxing material during pelletization proposes an route usage waste. pellets were manufactured with different binary basicity values (CaO/SiO2) (0.15-0.45) bentonite (0.5-0.7 wt%) fixed carbon (0.5-1.1 contents. ...

Integrated field studies on environmental levels, bioavailability, biological exposure, and effects SUMMARY Iron-ore is the source of primary iron for the world's iron and steel industries. Almost all (98%) iron-ore is used in steelmaking. Australia and Brazil together dominate the world's iron-ore production, while China is the world's largest iron-ore consumer. In Brazil, iron-ore mining is m...

Results of reducibility tests of reduction conducted on iron ore pellets with carbon are presented in this work. Work done is centered on reduction kinetics using carbon as reducing agent with conventional heat supply (heat transfer process) compared with reduction kinetics where heat is supplied by microwaves to the whole volume. Ore used in this work is called "Alzada" which has reducibility ...

In this study, the integrated iron and steel plant mill scales prepared to concentrate in different ratios by blending with hematite character ore. CMC was used as binder coke will be reductant. The calcite added such a way that basicity ratio is 0.7. pelletizing machine pellet blends containing at then drying temperature of 150 °C. 28 kg / compressive strength obtained pellets from 100% scales...

Here, we report the draft genome sequence of the betaproteobacterium Ideonella sp. strain A_228. This isolate, obtained from a bog iron ore-containing floodplain area in Germany, provides valuable information about the genetic diversity of neutrophilic iron-depositing bacteria. The Illumina NextSeq technique was used to sequence the draft genome sequence of the strain.

The impact behavior between the charge and lifter has significant effect to address the mill processing, and is affected by various factors including mill speed, mill filling, lifter height and media shape. To investigate the multi-body impact load behavior, a series of experiments and Discrete Element Method (DEM) simulations were performed on a laboratory-scale mill, in order to improve the g...
