【Introduction】： Silver flotation process of Xinhai includes three kinds of methods: flotation, flotation &gravity separation, flotation &cyaniding, while the flotation & cyaniding method is the most important process among the whole, silver concentrate can be get in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement and silver ingot can be finally get after the last process of electrolytic dissociation. Thus the process characterized by high recovery and economic benefits.
【Application】： Silver flotation process mainly applied for the recovery of silver and associated metallic minerals, silver including two categories: one is silver &gold , the other is copper, lead and zinc associated.
【Case】： A silvermine in Inner Mongolia, its beneficiation size can reach 500t/d, the actual production capacity is 750t/d. its main ore is Pyrite, chalcopyrite, gold, silver and other natural . Aimed at the existing problems and combined the production practice, Xinhai improved the technology of the process flow and adopted flotation &cyaniding process which is more convenient to operate.
