What is the role of arsenic in the mining industry - MiningFacts

Although some plants are able to grow in soil with high levels of arsenic, most do not grow as well or produce as much fruit as they would in uncontaminated soil. [7] With a few . Arsenic trioxide is obtained as a byproduct from dusts and residues produced during the treatment of other metal ores such as gold and copper.

Treatment of Refractory Gold Ores | SpringerLink

Abstract. Problem ores that yield low (say less than 80%) gold recovery by cyanidation when “normally ground” are defined as refractory. The term, as well as the technical methods used to treat such ores, are relatively new. Rose and Newman's very comprehensive book, The Metallurgy of Gold, does not even contain the.
