Jade Spring Ridge processing plant tailings Treatment Process Practice

, The laying of a square to increase the size of the settlement inclined tube. Pulp from the thickener into the middle to evenly into the chute with the bottom of coarse settling into the bottom stream discharge, overflow water together in the collection ponds, processing plant and then returns as a backwater. To improve the deposition process, to add to the slurry into the flocculation Jing to accelerate settlement. Jade Spring Ridge processing plant enrichment process used in the inclined tube shown in Figure 2. Ken Li Jing Yong ore mine set to dig sand anti-Tin Tin 2 chute pour tube concentration enrichment process size sedimentation tanks 5mX5.5mX ● ・ 8mt collecting tank for the 2mX5.5rnX. 8m. Inclined tube is 40ram. Pour tube enrichment process design and production indicators in Table 5. Inclined tube of about 360,000 yuan investment in the enrichment process, than the use of rake thickener save 2O million, and the return water pipe flooded can be reduced decline 5 ramp design to meet the production targets set dressing plant production requirements. After nearly a year of use showed that treatment option for inclined tube enrichment plant tailings. 6 of 1996 with investments in metallurgical industry design and construction of 43-step short construction period, small footprint, and save the water consumption of new support point. 3, problems and suggestions have been confirmed. Pai Mei process for treatment of dry processing plant tailings, stockpiles of coarse prolapse most of the easy-to-tailings. Tailings storage capacity to save. There are still remaining about 4O fine tailings slurry to deal with. Brings new problems, if sent to the usual tailings, due to fine granularity, to adversely affect the tailings dam. How successful this part of the dehydration of the tailings. Is to achieve all of the row of tailings, the total elimination of a huge investment in the key tailings. Jade Spring Ridge processing plant has use of the existing 12m outside the vacuum filter drum machine permanent filter test tailings. The results show that, due to permanent structural features of the vacuum filter and tailings in the coarse grain size and high content of fine particles, fine tailings poor permeability. Difficult to form a cake. Therefore, when the production had to overflow into the spiral classifier tailings. The fine grain size, easy to settlement, difficult to form a normal deposition Beach, and the order to save power consumption, dry exhaust tail process only intermittent use. T for the enrichment process, although inclined tube can return and to ensure adequate water quality requirements, but the elections in the tailings plant less than estimated. Lead to small size of the settlement, the result is forced to lower the concentration of the end of lies, Park here. The amount of slurry processed. Select plants from the ground leaving a certain amount of normal off the amount of tailings into consideration to ensure the concentration effect. As Ling Yuquan tailings processing plant size than Ying, inclined tube production is often gridlock grit mouth phenomenon, the storm of this, before entering the inclined tube prolapse of part of the coarse tailings. The normal use of the inclined tube and reduce wear and tear are the benefits of the sand pump. To sum up, indicating that the dry exhaust tail and ramps for travel reduction techniques have to deal with Ling Yuquan similar processing plant tailings, which is kind of tailings disposal and stockpiling found a way out. Taking into account the current situation, who wish to achieve true end of the dry row, should consider the following two methods. ★ ★ ★ ★ ★ ★ i welcome I from a homogeneous broom | broom. _ |. j * 3.1 spiral classifier overflow hang reprocessing, for the low concentration, fine tailings, should be concentrated dehydration. To improve the pulp density. Taking into account the impact of a small settling velocity, can be added flocculant, efficient and multi-stage thickener concentration and other measures to be dehydration, inclined tube enrichment facilities can be used as one of enrichment, in order to save investment. Higher concentration after the concentration of slurry, can be used for high-efficiency filter press dewatering filter. To achieve solid-liquid separation, which will merge the thickness of grain dry tailings deposited in the open pit, return all of reuse. 3.2 coarse and fine tailings mixed dehydration to facilitate the storage, transport, small processing plant can be used in the sedimentation tank dehydration, in order to save investment and operating costs. Sedimentation tank overflow into the inclined tube concentration, to obtain clear water. Inclined tube sedimentation tank bottom flow returns, a small amount of imbalance into the tailings. Tailings settling pond to reduce the water content, the need for transformation of the structure of sedimentation tanks in order to obtain better treatment results. Of course, the tailings disposal no matter that a program must be based on technical feasibility, economic rationality on the basis of adequate technical and economic feasibility before implementation. At the same time, should be enriched and fine-grained tailings filtration test, to explore its feasibility. 4 Conclusion dry tailings stockpiled on the deal, to eliminating costly tailings, mine production is a new topic on how the economy will be fine tailings dehydration is the key to achieving this vision. Fine-grained materials currently used to deal with common filtration equipment, high cost, the problem of low utilization factor in the cost-efficiency filtration equipment smell the world of fine tailings, before the process can take some optimization on the tailings dumps processing to achieve better economic efficiency.
