Key Points

To develop a method for the simultaneous separation of germanium and antimony from sulfide samples for isotopic analysis.
Utilized MC-ICP-MS for high-precision isotopic analysis.
Developed a chemical separation protocol for germanium and antimony.
Focused on Sb-rich sulfide samples, particularly those containing sphalerite.
Successfully separated Ge and Sb, allowing for accurate isotopic measurements.
Identified enrichment patterns of Ge and Sb in the samples analyzed.

Implication

Simultaneous chemical separation achieves isotopic analysis of germanium and antimony from sulfide samples, indicating their distribution.

Abstract

Germanium (Ge) and antimony (Sb) are critical metals that can be enriched in sphalerite of Pb-Zn deposits due to their chalcophile properties. The combined Ge-Sb isotopic systematics of these deposits...
