خبير الاتصالPrecious metals such as gold and silver are recovered from difficult-to-treat ores, particularly those containing manganese, by lixiviating using an ammonium thiosulfate leach solution containing copper, sufficient ammonia to maintain a pH of at least 7.0, and at least 0.05% sulfite ion, sulfite and thiosulfate requirements being maintained by the reaction in situ of
خبير الاتصالThe use of manganese in steel production is a double-edged sword, as the metals fortune is intimately tied to the steel industry. Whenever there is a severe downturn in steel-making manganese also suffers [5]. Hence, the need to develop a simple and practicable route for the processing and extraction of manganese from its ores is necessary.
خبير الاتصال1999年1月1日 Historically, research on thiosulfate leaching of precious metals ores has been focused on processing of difficult to treat ores. Thiosulfate leaching of ores and concentrates containing sulfide minerals, copper, manganese and preg-robbing carbon constituents has been evaluated.
