Arsenopyrite (FeAsS) is the most common As-bearing sulfide mineral. Under oxidising
conditions, such as those in mine waste systems, it breaks down to release acids of As and …

Abstract (Bio) Hydrometallurgy is a relatively economical and eco-friendly processing
technology for sulfide minerals. Sulfide minerals degradation at abandoned mine sites also …

This book presents an overview of the chemistry, geology, toxicology and environmental
impacts of arsenic, presenting information on relatively common arsenic minerals and their …

This study investigates the natural processes that control concentration of detrital minerals
and consequently chemical elements in river sand. The novelty of our approach consists in …

Arsenic (As) is one of the most investigated elements worldwide due to its negative impact
on the natural system. Its geochemical behavior depends on several geogenic processes …

A historic antimony smelter site at Endeavour Inlet, New Zealand has smelter residues with
up to 17 wt.% antimony. Residues include coarse tailings (cm scale particles, poorly sorted) …

The main sulphide minerals that serve as gold carriers in low-grade raw materials are pyrite
and arsenopyrite. Traditional methods of processing such refractory raw materials rely on …

In a natural analog study of risks associated with carbon sequestration, impacts of CO 2 on
shallow groundwater quality have been measured in a sandstone aquifer in New Mexico …

A thermodynamic dataset for arsenic species in As–O–H–S–Fe–Ba system was compiled
from the literature. Using this dataset, Eh–pH diagrams for the systems As–O–H, As–O–H–S …

The environmental impact of toxic metal contamination from legacy mining activities, many of
which had operated and were closed prior to the enforcement of robust environmental …
