Arsenic Speciation in a Contaminated Gold Processing Tailings Dam

Geostandards and Geoanalytical Research, 2000
Gold recovery in ores containing arsenopyrite releases significant amounts of arsenic into the environment due to mineral processing and oxidation during storage. The extent of arsenic weathering in a tailings dam has been investigated. Speciation of As in surface and pore waters and pond sediments showed that for gold tailings in the dam, As ...

Failure Management in a Gold Mill Tailings Treatment Process

2021
Despite various existing asset management methodologies, there are still many areas where they are yet to be implemented. This is mainly because they are not customized methodologies and their implementation, in many cases, generates several theoretical-practical gaps and inconsistencies, which hinder their application.
