On Mining and Processing arsenic - The Rockyard Restaurant

mining - on mining and processing arsenic Arsenic occurs in pure form only in small deposits. It occurs in many minerals, and usually is obtained as a byproduct from the mining, processing and refining of other minerals. Common arsenicbearing minerals include arsenopyrite, conichalcite, enargite

The Role of Arsenic in the Mining Industry

2015-5-14  The rate of arsenic release from sulfide minerals can be accelerated by mining activities, which expose the minerals to weathering processes during excavation. Also, arsenic can be mobilized by weathering of outdoor stored waste byproducts produced during the subsequent metal value recovery process.

Mining activities generate a large amount of solid waste and acid drains that contain heavy metals in high concentrations. In wastewater of gold mines from Southern Ecuador (Portovelo), arsenic concentrations between 4.8 and 27.5 μ g/L have been detected. In this context, the objective of this study is to prepare a technosol, which was used in the capture of arsenic dissolved in the acid drains.
