Behaviour of cobalt during sulphuric acid pressure leaching of a limonitic laterite
TLDR
In this article, a titanium autoclave equipped with acid injection and sample withdrawal units was employed for batch pressure leaching of raw limonitic laterite and the evolution of the nature of solid products during leaching were thoroughly investigated using Transmission Electron Microscopy (TEM).About:

Sulphuric acid pressure leaching of a limonitic laterite: chemistry and kinetics
TL;DR: In this article, it was observed that limonite consists of aggregates of needle-like particles of goethite compacted together, and the grain model was finally proposed to best describe nickel dissolution kinetics.

Systemic effects of implanted prostheses made of cobalt-chromium alloys
TL;DR: Systemic effects of Co-Cr alloy/polyethylene hip joint prostheses were investigated using instrumental neutron activation to determine the concentrations of up to 16 elements and showed massive Co enrichments as a consequence of implant corrosion.
