201661 · Abstract The pH-dependent leaching of antimony (Sb) and arsenic (As) from three typical Sb-bearing ores (Banxi, Muli and Tongkeng Antimony Mine) in China was assessed using a pH-static leaching experiment. The pH changes of the leached solutions and pH-dependent leaching of Sb and As occurred in different ways. For the Banxi and …

20231219 · in 2019. The plant was set up to treat 40,000 tonnes per year of antimony-gold concentrates producing 20,000 tonnes per year of antimony metal and antimony trioxide, making it the largest antimony roaster outside f China. Nevertheless, according to experts, most of the conversion of antimony ores into antimony metal or ATO would occur …

Abstract: Efficient evaluation of antimony ores, which are on the critical raw materials list due to the supply risk by the European Union, is an important necessity. In this context, ore preparation and enrichment processes are very important during the process from ore to metal. Especially for sulfide antimony ores, the most common beneficiation method is …

201726 · The ores of copper are usually associated with minerals containing arsenic, antimony and bismuth. Whatever the means adopted for extracting the copper, these metals are usually found, to a greater or less extent, in the product. There is, however, usually some elimination in the various metallurgical operations to which the ores are subjected, and …
