Arsenic: Will it take the shine off the red metal?

2020-9-5 · Capturing arsenic in early stage processing has cost advantages compared to processing high arsenic waste. Due to the relatively low capture rate of standard copper sulphide processing methods such as flotation, it cannot be applied to high arsenic ores in isolation. Several processing methods exist, as seen

Mineral Processing - an overview | ScienceDirect Topics

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Treating Arsenic and Selenium in Mine-Influenced Waters

2019-1-22 · Acid rock runoff or acid mine drainage requires treatment because, untreated, it makes water uninhabitable for aquatic life. Contaminants such as arsenic and selenium can occur in both acid mine drainage and mine-influenced waters that have a neutral pH, depending on local conditions. In both cases, these two contaminants also require treatment.
