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...

A study on the quantitative leaching of iron ore in hydrochloric acid solution has been undertaken. The elemental composition of the iron ore was also carried out using ICP-MS technique. The major elements in the iron ore include: Fe(66.7%); Al (0.2%); Si (5.2%); Ti (0.02%) and O (28.0%). Some traces of V, Ni, Zn, Ce, Cr, La, Y and Zr were also found. The effects of contact time, acid concentra...

Purpose. This research aims to promote the assay of iron and reduce phosphorus grade final DRI. Methodology. A high-phosphorus oolitic ore from Gara Djebilet deposit underwent procedure coal-based direct reduction (coal-based DR) followed by wet low-intensity magnetic separation (WLIMS). The effects temperature, periods time Na2SO4 dosage on removal, metallisation degree recovery rate were trie...

Pseudonannolene spelaea n. sp. is the first strictly cave-dwelling species described for the family Pseudonannolenidae. It is found in iron ore caves in the Brazilian Amazon. The family Pseudonannolenidae is exclusively Neotropical and frequently found in caves of Brazil, from which 20 species are known. The new species is compared with its congeners and with related cave-dwelling species. The ...

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...

Iron ores are used in blast furnace for the production of pig iron; AGBAJA Iron ore has an estimated reserve of over I billion metric tonnes. Unfortunately, this large reserve cannot be utilized for the production of pig iron due to its high sulphur contents. This work studied the reduction of sulphur content of AGBAJA iron ore. Acid leaching methods were used to reduce sulphur contents of the ...
