Chemical Phase Analysis of Arsenic Ores—A Study on Selective Separation Conditions of Orpiment and Realgar [PDF]

Yankuang ceshi
As a rich symbiotic mineral resource, orpiment (As2S3) and realgar (AsS/As2S2/As4S4) are common sulfide minerals of arsenic. However，due to their similar chemical properties, the chemical phase analysis method of arsenic has always taken these two ...

Properties of realgar bioleaching using an extremely acidophilic bacterium and its antitumor mechanism as an anticancer agent

Biological Research, 2017
Realgar is a naturally occurring arsenic sulfide (or Xionghuang, in Chinese). It contains over 90% tetra-arsenic tetra-sulfide (As4S4). Currently, realgar has been confirmed the antitumor activities, both in vitro and in vivo, of realgar extracted using ...

Cleaved Natural Realgar (AsS) by XPS

Surface Science Spectra, 2006
Realgar (AsS) is an arsenic ore mineral formed in low temperature hydrothermal veins and hotsprings, and commonly associated with other arsenic minerals such as orpiment (As2S3). It is of significance environmentally in areas affected by acid mine drainage where oxidation causes both the generation of acid and the release of arsenic in surface water ...
