| difficult. At present our comprehensive utilization rate | | | | "Planning" introduced a number of new technologies |
| of industrial solid waste 60%, while the total amount | | | | will drive R & D, identify key projects utilization |
| of metal tailings pile at least 80 million tons, less than | | | | of metal mine tailings 500 to 700, with a total |
| 10% utilization, especially utilization of iron ore tailings | | | | investment of 54 billion yuan. |
| and tailings lower non-ferrous metals, significantly | | | | These include type V-Ti magnetite tailings residual |
| lagging behind other bulk solid waste, industrial output | | | | vanadium, titanium, iron and other valuable metals |
| in China has become the largest, comprehensive | | | | separation and recovery efficiency, Bayan Obo iron |
| utilization rate of the minimum of waste. | | | | tailings residual niobium, rare earth and other |
| Tailings brought a lot of stockpiling the waste of | | | | associated metals separation and recovery efficiency |
| resources, environmental pollution, safety hazards and | | | | and so on. At the same time will overcome the many |
