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 …

The past twenty years or so have seen dramatic development of the experimental and
theoretical tools available to study the surfaces of solids at the molecular (“atomic …

This report describes a new form of arsenian pyrite, called As3+-pyrite, in which As
substitutes for Fe [(Fe, As) S2], in contrast to the more common form of arsenian pyrite, As1 …

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

The interaction of As (III) with micron-sized, mechanochemically sulfidated zero-valent iron
(S-mZVI bm) has been studied under both anoxic and oxic conditions. The As (III) removal …

Metal sulfides are the most important group of ore minerals. Here, we review what is known
about their compositions, crystal structures, phase relations and parageneses. Much less is …

We used a mixed flow reactor system to determine the rate and infer a mechanism for
arsenopyrite (FeAsS) oxidation by dissolved oxygen (DO) at 25° C and circumneutral pH …

Arsenopyrite (FeAsS) and enargite (Cu3AsS4) fractured in a nitrogen atmosphere were
characterised after acidic (pH 1.8), oxidative dissolution in both the presence and absence …

The oxidation of pyrite under acidic conditions, an important process leading to the formation
of acid mine drainage, has been the subject of intense research yet remains incompletely …

Conventional X-ray photoelectron spectroscopy (XPS) and synchrotron radiation XPS
(SRXPS) were used to probe the chemical state properties of stibnite (Sb2S3), a large-band …
