Availability, Toxicology and Medical Significance of Antimony
2. Mineralogy, Geochemistry, and Availability of Antimony. It is necessary to understand the geological properties of antimony in order to properly assess the impact of related geological processes on public health [28,29].Antimony exists naturally in the Earth's crust and is released into the environment via both natural and mining–industrial …
The Impact of Physical Properties on the Leaching of
This study reports on the assessment of the impact of antimony mine wastes from Xikuangshan (XKS) Antimony Mine in Lengshuijiang City, Hunan Province. We focus on the leaching of a number of potentially toxic elements (PTEs) from residues from the processing of antimony ore. The PTE content of ore processing waste and solutions …
Insights into the biogeochemical transformation, environmental impacts
