Beneficiation of nickeliferous laterite by reduction roasting in the presence of sodium sulfate

G Li, T Shi, M Rao, T Jiang, Y Zhang - Minerals Engineering, 2012 - Elsevier
In this paper, the reduction roasting of laterite ore in the absence or presence of sodium
sulfate was carried out for nickel beneficiation by wet magnetic separation. Sodium sulfate is …

Synthesis of single-phase L10-FeNi magnet powder by nitrogen insertion and topotactic extraction

S Goto, H Kura, E Watanabe, Y Hayashi… - Scientific reports, 2017 - nature.com
Abstract Tetrataenite (L 10-FeNi) is a promising candidate for use as a permanent magnet
free of rare-earth elements because of its favorable properties. In this study, single-phase L …

Solar nebula magnetic fields recorded in the Semarkona meteorite

RR Fu, BP Weiss, EA Lima, RJ Harrison, XN Bai… - Science, 2014 - science.org
Magnetic fields are proposed to have played a critical role in some of the most enigmatic
processes of planetary formation by mediating the rapid accretion of disk material onto the …

Fe–Ni composition dependence of magnetic anisotropy in artificially fabricated L1 0-ordered FeNi films

T Kojima, M Ogiwara, M Mizuguchi… - Journal of Physics …, 2014 - iopscience.iop.org
We prepared L1 0-ordered FeNi alloy films by alternate deposition of Fe and Ni monatomic
layers, and investigated their magnetic anisotropy. We employed a non-ferromagnetic Au …

Meteorite evidence for partial differentiation and protracted accretion of planetesimals

C Maurel, JFJ Bryson, RJ Lyons, MR Ball… - Science …, 2020 - science.org
Modern meteorite classification schemes assume that no single planetary body could be
source of both unmelted (chondritic) and melted (achondritic) meteorites. This dichotomy is a …

An ancient core dynamo in asteroid Vesta

RR Fu, BP Weiss, DL Shuster, J Gattacceca, TL Grove… - Science, 2012 - science.org
The asteroid Vesta is the smallest known planetary body that has experienced large-scale
igneous differentiation. However, it has been previously uncertain whether Vesta and …

Iron meteorites: Composition, age, and origin

ERD Scott - Oxford research encyclopedia of planetary science, 2020 - oxfordre.com
Iron meteorites are thought to be samples of metallic cores and pools that formed in diverse
small planetary bodies. Their great diversity offers remarkable insights into the formation of …

Long-lived magnetism from solidification-driven convection on the pallasite parent body
