Manufacturers of zinc concentrate grade increased research and application


5257% 6.07% increase over pre-application of zinc concentrate zinc to the product requirements. By production practices. Further evidence of the feasibility of two-step production of sub-selections: First, off drug effect, and pyrite have been effectively suppressed music. Grinding in the custodial alkali (pH = 8) and high alkaline (pH = 125) selected the interaction of Jing, the step of separating off the drug effect is obvious, the two-step sorting effectively inhibited step was made floating pyrite , alkali pyrite, galena. India: pyrite and other impurities have been points race throw (the transfer p. 45) 1998.4 45 foreign metal ore beneficiation, end table China's specific national conditions. Development of clean coal technology in China's basic strategy is: (1) for the Chinese coal varieties, big and poor quality of cut used in Wei characteristics of industrial users in the development of clean coal technology should be concrete reality, due to coal should, with speed because the system should use the appropriate clean coal technologies. (2) after the praise for Taiwan to strengthen international asked. At present the gap with the developed countries, mainly in technology news available size and maturity of technology, through the international voice for, to accelerate China's development of clean coal technology. In some areas, may merit the introduction of sophisticated technology. (3) in the development of clean coal technology should be coordinated, focused on big coal, key technologies and mature technologies in three areas. 5 knot spectrum of clean coal technology is a complex systematic project, which limited costs related to the human stage (on the next page 21) system, to improve the 7-speed floating effect. Second, the adjustable range of solid quality control. Promote the two-step sorting load balancing, improve the recovery of crude zinc effect, reduce the production business management more difficult. Two-step separation, can make the step separation of zinc concentrate grade increased from 45% to 35% of the above adjustments, reducing the normal operation of mixed floating bubble Pitt cut the impact of further sorting. The sorting step is relatively stable foam blowing from the surface to ensure that the two-step sorting coarse-grained load balance to promote rapid zinc Ang is floating. Recovered in a timely manner. And a step to avoid the party producing thrust for separation due to fluctuations in surface loss of zinc metal on the float easily whipped the problem of zinc tailings,true religion outlet, so easy to achieve production targets summer. The investigation determined that zinc production is distributed rate of 2017 percent ounces of +02 mm grain japonica rice grain Procellariiformes zinc recovery from 52% to 89%. From the application before (96 Zhuo January to June) and after application (96 Zhuo 7-12) of the total production target can be further confirmed 7-December cumulative recovery of zinc up to 8317% innocent increased 1415% over 1-6 months : set of total zinc grade of 4925% compared with January to June increased 486% bone. Visible. Using two-step zinc sulfur separation process is to improve the quality of zinc concentrate and effective measures. Reasonable use and environmental problems of human existence,######## oakley sunglasses, which to hang Qiang social concern and involvement. Development of clean coal technology Qiang layered attack to the gradual and orderly opening morning, the now mature technologies, such as the implementation of the coal mining, dressing, smelting, electricity,herve leger sale, construction and integration of technology, to promote high technology, especially technology mature technology, but lack of funds, should actively build demonstration plant, the technology is less mature stage in the research thrust should claim to support Pitt. References I virtual Yuqi. The development of clean coal technologies for China if in thought. Clean coal technology, I996 (1): 6 an I12 Chen Jiaren. China's coal and clean coal technology used heir. Clean coal technology 199616-194.2 the economic benefits of new technology applications handled by Zhuo amount of 15 million t of ore size, grade of 9.03% zinc calculated. Improve the effectiveness of zinc concentrate grade increased to 219. oo million. Zinc recovery rate of increase in efficiency as the 613.32 million yuan, buckle two-step separation process see the cost of production 127O1 million on technology cost 7.0531 million yuan in profile. 5 Conclusion (1) two-step separation process can not only solve a multi-chrome stone multi-metal sulfide ore flotation interaction problems and improve the quality of zinc concentrate and recovery of Ku, and low production costs, economic rationality. (2) improve the technical measures. Camp management conditions have improved,tods shoes outlet, and further strengthen the stability and reliability of production. (3) eat refined metallurgical principles to promote and improve the smelting process, reduce production costs, increase speed rule of technical indicators.
