Abstract: The partial roasting of high-arsenic copper concentrates at 973 K/998 K (700 °C/725 °C) under controlled atmosphere can remove > 95 pct of the arsenic contained in the concentrates, leaving a calcine with 52 to 68 wt pct bornite, 10 to 13 wt pct… read more here.

Abstract: The typical disposal of high-arsenic waste acid is at the expense of discharging a large quantity of hazardous solid waste, resulting in secondary pollution of arsenic. We propose a modified lime/ferric salt method for high-arsenic… read more here.

Abstract: The prevalence of arsenic (As)-affected groundwater in the Late Pleistocene and Holocene aquifers leads to serious arsenicosis worldwide. However, the geogenic foundational processes underlying the high As aquifers remain elusive. Here we present joint lines… read more here.
