Tailings dry row definition

The dry tailings of tailings are processed into a tailings storage and then discharged into the tailings pond through a concentrated dehydration process through the concentration and dehydration process after the extraction of the valuable substances in the ore is carried out by the beneficiation process, and then the materials are prepared to a moisture content (mass percentage) of 10%±2. A process used to dump or recycle a dump.

The main process of the program-controlled automatic hydraulic chamber filter press is: concentration equipment + dewatering equipment + conveying equipment; process equipment selection and transportation mode through the material properties, specific gravity, particle size distribution, treatment volume and other indicators of the tailings slurry And the geographical conditions of the site are determined.

Its main significance is to alleviate the pressure of tailings storage capacity, reduce the safety hazard of tailings ponds, increase the means of tailings reuse, and obtain a green environmental protection mine system.

The main problems: dry tailings discharge process ills that most difficult tailings dewatering fine grade material, especially lies in the choice of dry iron ore and heap gold mine, gold production due to the small size tends to be more need for particle size distribution, Most of the iron ore is due to the fact that there are many soil components in the open pit mining. As a result, it is difficult to dewater the fine-grained materials. Many tailings enter the cyclone, then enter the vibrating screen, and then feed into the thickener. The bottom of the thickener returns to vibration. Sieve, so that the processing volume and operating load of the thickener are reduced, but it causes the tedious process of thickening of the thickener, the infinite circulation of fine-grained materials and the increasing number of grades, due to the characteristics of the thickener to fine-grained materials (- More than 200/80% can cause this problem. The thickening effect itself is not good, so the sedimentation process is long and the underflow concentration does not meet the requirements of the index. The same results are obtained for the thick pool and the sedimentation tank. Exploring a pair of crafts, first of all we have to go the right way, the problem is so obvious that it can not face up, the results can be imagined. 1 The above process is only the actual problem in the correct process. 2 The process is cumbersome and the process is abrupt. 3 We explored not only the process of tailings dry row, but also other related process links (stacking, re-stocking Utilization, environmental protection, etc. 4 The processing of fine-grained materials is gradually reduced rather than increased by process means, which requires the choice of process mode and understanding of process equipment and the choice of process equipment.
