The main component of the lead-zinc tailings are quartz and suicide sericite. Except the methods of stockpiling in tailings pool, dry-tailing stacking and mine filling, Xinhai will also apply gravity separation, flotation separation, magnetic separation, gravity - flotation separation, and other process to recycle the valuable elements.
In this paper, the mineral processing experimental study on the flotation tailings which are stored in the tailings pond of a copper-molybdenum mine is conducted, with a large content of slimes and kaolinite in the tailings and the fine particle sizes and poor locked particles of most of valuable minerals disseminated in the gangue minerals taken into consideration.
It is a technology that recycles the filtrate to realize the water resources recycling in processing plants with pressure filtration process, and get rid of most cyanide in the tailings. For other elements in the gold tailings, Xinhai applies magnetic separation, flotation and other methods to deal with.
Jul 29, 2021· In this study, a process of magnetizing roasting followed by magnetic separation was investigated to separate or recover tin and iron from the high calcium type tin, iron-bearing tailings ...
