GGR Handbook of Rock and Mineral Analysis Chapter 16 Nano‐Imaging for Advanced X‐Ray Fluorescence and Absorption Spectroscopy Applications

Geostandards and Geoanalytical Research, Volume 49, Issue 3, Page 495-533, September 2025.
Key Points Synchrotron nano‐imaging is necessary to locate elemental nanophases. Trace metal quantification requires high sensitivity nano‐XRF. Trace metal speciation relies on nano‐XANES using nano‐XRF. This chapter (Nano‐Imaging for Advanced X‐ray Fluorescence and Absorption Spectroscopy Applications) is a contribution to the Geostandards and ...

Study on Floatation Separation of Molybdenite and Talc Based on Crystal Surface Anisotropy

Separations
Talcose molybdenite resources are abundant but resource utilization is low. The floatation separation of molybdenite (MoS2) and talc is challenging due to their similar natural hydrophobicity and layered structures.

Environmental assessment of potential industrial waste management in the Czech Republic

Journal of Industrial Ecology, Volume 29, Issue 4, Page 1185-1196, August 2025.
Abstract In contrast to municipal waste, the much larger quantities of industrial waste are less frequently addressed, both in legislation and in life cycle assessment (LCA). However, LCA studies can identify opportunities to reduce national environmental impacts by improving the management of industrial waste, and they can inform legislation that ...
