This research is aimed at the up-gradation of indigenous Pakistani iron ore, i.e., Dilband ore (hematite), by utilizing common metallurgical processes. First, magnetic properties were determined. Initially, samples contained 34 wt. % Fe in addition to other gangue materials. Therefore, was subjected a high-temperature reduction roasting process between 800 °C and 1000 °C. Additionally, separati...

We briefly review a modular algorithm to perform row reduction of a matrix of Ore polynomials with coefficients in Z[t], and describe a practical implementation in Maple that improves over previous modular and fraction-free versions. The algorithm can be used for finding the rank, left nullspace, and the Popov form of such matrices.

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...

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.
