2019. 8. 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
2015. 5. 14.· Arsenic trioxide is obtained as a byproduct from dusts and residues produced during the treatment of other metal ores such as gold and copper. [25] The arsenic trioxide can be purified on site or sold to a refinery. [7] China is the world’s leading producer of arsenic (25,000 tons in 2014) followed by Chile (10,000 tons) and Morocco (8,000 tons).
2020. 4. 1.· grade of arsenic in concentrate. Overgrinding led to desliming and more loss of As in tailings. It was established that allylalkylthionocarbamates and dialkyldithiophosphinates could be considered as prospective reagents for tennantite ore flotation.

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 right, and in future higher arsenic volumes will likely be treated by a mixture of solutions, from early stage arsenic separation during leaching to roasting and smelting in modern smelting

2014. 11. 1.· Arsenic minerals pose a problem for copper flotation concentrates since they are often associated with copper minerals, display similar flotation behaviour to copper minerals and therefore report to final copper flotation products. Despite extensive research, the rejection of arsenic minerals in copper flotation is still a challenge.
2012. 10. 4.· fied as follows (Bulatovic, 2007): a) sequential copper, lead, zinc flotation method where the copper, lead, and zinc are sequentially floated to produce separate copper, lead and zinc concentrates, b) bulk flotation of copper and lead followed by zinc flota-tion from the bulk tailings. The copper–lead separation is performed on the upgraded
