Politon arsenic removal technology
Thread Content
Dear sea friends: Does anyone have any information on Polytone’s arsenic removal technology for processing high-arsenic, sulfur-rich gold ores? I have an urgent need. Thank you first.
Does the Polytan arsenic-removal technology mentioned above for processing high-arsenic, sulfur-containing gold ores refer to the smelting technology used by the Swedish company Polytan to treat such ores in Caldo furnaces? Relevant information can be found by searching on the forum.
Reply to 2# Lu Doujiang: Arsenic-containing gold concentrate is roasted in two stages – magnetization roasting for arsenic removal, and oxidation roasting for sulfur removal. After arsenic is recovered from the flue gas using bag filters, it is used to produce acid. What are its main technical control conditions and indicators? Tongling Nonferrous Metals has already adopted it; I wonder what the results are?
