Iron Mine Tailings good transmission efficiency to improve the way

Transformation. Tailings concentration first increased to 15 to 20, and then again into the high concentration tailings. While two-stage enrichment process, the beneficiation process in the selection of the coarse grinding stage of Tailings and tailings were selected for enrichment, and its advantage is to remove a thick concentrated tailings. Second former times to reduce the load concentration, reaching a high concentration by the concentration of condensed Paul Sec overflow water. 4) improve the utilization of mineral tailings return water production, including new water and tailings water return in two parts. Backwater general energy use in the production of water than the use of new low energy consumption. Liang Shan Iron Mine in June 1988 to build a tailings return water projects, including the pool and back to the pump house back, the installation of water pumps (2 sets) and the new return pipe (steel pipe Dg300mm. Length 1400m). Production practice shows that not only improve the rate of tailings using the backwater and J, and solve the situation of water shortages during the dry season, and dressing in order to reduce production costs and energy savings provided with, t /: /-J Ge, mine design and folding rule Building 5, 1993 Gold Experience Ping exclusion of certain gold mine design intoxicated adjacent homes Zhu TD7_} 【Abstract】 In this paper, Zhou Shao-rock base, Sichuan ten ORE T'E0: dollars. Ten new development in this project, designed with barrier slime cyanidation - Zinc bad set by - Box mud smelting technology, engineering in July 1993 successfully completed and commissioned. il! ~ t of this project, including design and engineering services, has made mines left on the rock base the design of mining experience. Gold Ping gold deposit is located in Kangding County of Sichuan Province Ganzi. Mine is a natural location in eastern Qinghai-Tibet Plateau, the middle of the snow mountains, elevation above sea level 1400 ~ 2300m. The county is mainly Tibetan, Han, Hui, Yi and other ethnic minorities in the mixed counties. Economic and cultural backwardness, the county in 1987 was 29.65 million yuan of industrial and agricultural output value. The industrial output value of only 9.45 million yuan. In order to expand production capacity in Sichuan Province of gold, to foster economic development in minority areas Ganzi Prefecture, Sichuan Province, according to Golden State Gold Administration Bureau and the arrangements, Changsha Metallurgical Design and Research Institute from l989 began in May and lasted two years, has completed the \\Determine the concentrator designed daily processing ore 75t, re-floating process for the joint processes, products, refined gold and heavy as part of the float concentrate. After nearly two years of construction of the building and commissioning, the project was July 1993 through the completion and acceptance, test production. Gold gold floor construction in Sichuan Province's first rock gold mine, Changsha Metallurgical Design and Research Institute is designed to meet all slime concentrator for the first time replacement of a gold cyanide mixed with a zinc smelting and roasting a cyanide gold concentrate melting process of a gold leaching mud. So do a good job designing the project, the development of Sichuan Province, the construction of rock gold mine, and rock gold mine for future development are important design business. Some are designed to concentrator tube experience in the post above to correct me 1 Ji, research, optimization of the design process is a mixture of rock gold gold floor hydrothermal altered rock of a quartz vein type gold ore. Sulfur ore industry types are ram-type gold ore of natural gold by ore texture and structure and mineral paragenesis is divided into four types of gold ore limonite, yellow iron ore, gold ore veins, polymetallic sulfide quartz vein type gold favorable conditions . 5) The application of high sand pump current, high wear resistance are Warman pump sand pump, oil pump isolation, 250PN sand pump, etc., from the performance parameters and the use of point of view, can not only replace the pump PN-type impurity, PH-and Ps-type, etc. old products, and its operational efficiency and service life are greatly improved, there are no further use this highly efficient factories, mines sand pump wear. For example, Miyun, Beijing-based iron ore by 6s ~ H Warman pumping tailings, the life of 1539h, than the original 8PH-type sand pump life expectancy has increased 4 times i Fu Shan Iron Concentrator in 1987, with m ~ 1oo/4o oil pump to replace the original 6PNJ isolation plastic pumps, tailings concentration from 20 to 40, life 228h, section owned 333,000 yuan per year. Liang Shan iron ore tailings booster pump station 8PH-type sand pump use, low efficiency, and wear parts (impeller, retaining plate, pump casing, etc.) Life is short, the maintenance workload. 8PH-type sand pump wear and tear, Young head decreased volume and, thus, often appear less sand pump capacity, tailings slurry spills and other phenomena, not only pollute the environment but also affect the normal life. To do this in increasing concentrations of tailings conveying the same time, should be used 8/6E ~ AH-type Warman pumps (Q = 600m ~ / h, H a 57m), or 1o / 8. ~ R ~ AH-type Warman pump (Q a 600m. / H, H = 61.5m), replace the tailings booster pump station in the 8PH-type sand pump. This would improve the operating efficiency and reduce maintenance costs.
