Kunming Iron and Steel Red Hill Iron 50 million t / a the successful completion and operation of mining projects

To gravity hill type programs, gifted programs plains-style election-style general program of peaceful three cases, investment in equipment and production of electricity from the area were compared, the results in Table l. Table 1 Comparison of equipment and electricity bills set the number of programs designed Zi amount of load set from Table 1 shows that gravity hill type programs, have location, investment in equipment and electricity are the least, this program is the program as a reference. Construction of flat-type concentrator, to create terrain is a price to pay, general investment and production costs have increased. The selection program of ground-type investment and lower tariffs, flat-style general election gifted program without comparison, more investment in equipment and the electric bill. Flat-type concentrator design, using flat-type election gifted programs good. Table l shows from one side of the design of relatively well-optimal selection is necessary. . 5 Conclusion construction of ground-type concentrator, is not ideal and seek the ideal, that is never an ideal terrain, find the ideal plant effect. Design of flat-type concentrator, not just equipment and equipment installation platform based on the level, together with the lifting equipment to compensate for the adverse terrain, and a multi-program comparison optimal selection problem. This example is designed to process flat-type single magnetic concentrator, flotation, or re-election if there are such processes, the basic method used in much the same. Design of flat-type concentrator disadvantage is universal, but each concentrator have the particularity of the design to analyze specific issues, careful design, brainstorming, and more optimal selection program comparison, only more satisfied with the design of products in order to build more good ideal concentrator.

Kunming Iron and Steel Red Hill Iron 5O million t / a the successful completion and operation of mining projects in Kunming Iron and Steel (Group) Co., Ltd. Iron Mining Engineering Dahongshan l2 on 31 January 2002 successfully put into operation, which marks the western development under the guidance of macro-economic policies, China's iron ore resources in the development of a new round has started. Kunming Iron and Steel Dahongshan Iron is the largest and most important raw material base. 5O million t / a mining project is the development of iron ore Dahongshan preliminary works to soon start construction of the guidance 40O million t / a mining, the election process in the design and production technology parameter. The project is a key project in Yunnan Province, from Kunming, Changsha Metallurgical Design Research Institute and the Joint Research Institute of Nonferrous Metals Engineering Design. Underground mining, mining, mineral processing mill with a ball from a semi-weak magnetic intensity magnetic separation stage grinding of a selection process, using PLC focus concentrator operation, grinding process automation and other advanced equipment, ensure the optimization of mineral targets. Project from March 1, 2002 start, which lasted ten months will be completed and put into operation a success, process flow, concentrate qualified. This shows that the design is successful, Kunming Steel's management level is high, the history of mine construction in China is rare. Kunming Steel's overall steps in accordance with Department of Dahongshan Iron 4OO million t / a mining, ore and concentrate long-distance pipeline project will be put into operation in 2005. , (Tao Dejia) environment-friendly mining mineral processing technology by Breakthrough Technology Co., Ltd. Beijing ensure the development of the natural environment with our own intellectual property rights of an environment-friendly mining mineral processing technology, capable of efficiently sorting sludge, effectively breaking the existing re- selection of technology and equipment for fine and micro-fine mineral recovery limitations. Mine is now used by ordinary centrifugal concentrator only common metal ore roughing, while preserving natural centrifugal gravity concentrator analysis by separation from the sorting principle, applicable to the proportion of differences in mineral separation, which not only apply to ordinary metal thick Select. More suitable for the recovery of heavy metals, especially for the micro-fine mineral mud sorting. '(Magazine correspondent)
