Ore than one hundred percent not content ore, which contains a lot of impurities, such as silt. To elect ore, the impurities must be removed, this would require concentrator beneficiation processing. Beneficiation process: the concentrator, the first original stone crushing, then washed through the inside of the device so that the ore and sand isolated, complete dressing. However, this will produce washing wastewater, due to tailings water contains a lot of sediment, can not meet emission standards. Must be processed, after the standards before discharge, or recycling. Tailings waste water treatment, you must use the washing flocculant - polyacrylamide, is sediment deposition in the water, forming a mud separation, so as to make the wastewater clarification, to meet emission standards, or recycling, more cost savings.
