ore processing for arsenic

Arsenic in Complex Orebodies Ausenco

Methodology and Results A complex ore system was selected which had various levels of arsenic as enargite. Two ore samples with different arsenic levels, HAS (250 ppm) and LAS (100 ppm), were selected to provide a range of arsenic level. Size by size mineralogical analysis was performed by Mineral Liberation Analyser (MLA).

Arsenic in Complex Orebodies Ausenco

There is an increasing trend in the extraction and development of copper resources from complex deposits. The complex deposits pose mineral processing challenges, as they often contain low grade copper ore, relatively large quantity of clay minerals, complex texture, very fine disseminated ore, high amount of pyrite, and high level of impurity elements such as arsenic.

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

2020-9-5  Arsenic is a poisonous element found within minerals at many of the world’s copper mines. As a consequence of sulphide ore processing, arsenic is concentrated along with copper; this becomes more acute as the in-situ grade increases. The largest copper supply region in the world, Latin America, has high arsenic content in many of its ageing

Bio-oxidation of Arsenopyritic and Pyritic Containing

Being the most common sulfide minerals, Arsenopyrite and pyrite under oxidizing conditions breaks down to release acids of As and S into the environment, leading to acid mine drainage with high concentrations of dissolved As. In this research, the dissolution of gold ore (with FeS2 and FeAsS as the main sulfides) from Tianli gold mine, Liaoning province, China was investigated.
