| Abstract: |
| Yueyang Ag—polymetallic Mine first applied high concentration and all automatic flow of silverScopper whole tailings cement filling technology in precious metal mines of Minnan mountains of Fujian,the concentration of the slurry achieves 70%,belong to the filling method of highest concentration of automatic flow tailings in Fujian province.Whole tailings slurry,cement and proper amount of concentrated water form high concentrations offilling slurryafter stirring,then automatic flow transport to underground stope to fill empty area through filling pipeline.It effectively guarantees the mine safety production,the ore recovery rate improve to more then 80%,and it also reduces backfilling emissions by 45% every year,saves the cost of the tailings 1.136 million yuan to 2.272 million yuan one year. |
