The second is the deep iron ore is magnetite, hematite, and the two mixed mineral composition, the ratio changed greatly, ring and mineral processing structures and equipment selection to adapt to these changes. the United States for refined PSI Mine pipeline design requirements concentrate particle size is less than 0.074ram greater than 8o. deep ore sorting process, although less than 0.074ram Ground 52, the period of weak magnetic separation to obtain large part of iron ore containing Fe63, however, the ancestors of high intensity magnetic separation to obtain iron ore grade is 35. Weak 6 Concentrate and magnetic core are required to concentrate regrinding rent re-election, the former is mainly adapted transport, the latter mainly to improve taste. there is a sub-grinding mill and cooperation issues. I believe that the co-grinding as well. because the points wear, the magnetic ore and to adapt to changes in the proportion of oxide ore to be possible to separate the maximum amount according to their choice mill, the mill will inevitably cause many to choose; and co-grinding, the magnetic ore and will not change the total amount of oxide ores, mill capacity can be selected accordingly. In addition. min 69 grinding separation of weak iron available magnetic concentrates. intensity magnetic separation of iron ore, but 56, the final party may be combining two transportation, sorting out the meaning. of course. When combined grinding capacity of low intensity magnetic separation equipment to increase slightly, but increase the density machine concerned. is negligible. c. In the dressing experiment, the iron ore samples in deep geological work is left optional test core Cheung, 400 ~ 500m and 550 ~ 670m ore at l: 1 composition, the insufficient number of 400kg. pilot scale in the representation and the existence of certain defects. Therefore, some foreign companies to be re-collected bulk sample for testing problems. In this regard, I believe that needs attention, but it can not be a prerequisite for mine construction. called attention to . is to create conditions for possible additional validation tests, make the design more robust. deep stable iron mineral composition, the magnetite, hematite, and changes in the proportion of mixed ore, iron ore grade has fluctuated, but has made dressing experiment showed that there is no lack of qualified iron ore concentrate and iron recovery to reduce. only required for plant design by focusing on the proportion of mineral changes in the flow structure and equipment should be greater adaptive capacity . If the development project to proceed, then the ore mined to add more tests, then it will be properly stable and reliable. and for a time, saving manpower and resources. 3 outlook for the construction Dahongshan Iron ore 3.1 Dahongshan rich in resources, reserves are concentrated, is the development of Yunnan Province, the only condition with a large iron ore. its resources and reliable mineral optional properties, the construction of the external conditions include electricity, water and land use, have been implemented, with the development and construction own conditions and external environment. Kunming Iron and Steel in recent years has put a lot of manpower and material resources for construction preparation work. It also created the conditions for the construction of 3.2. Dahongshan iron ore buried under the holding points and development needs of Kunming Iron and Steel, construction scale 5O. ~ 550 万 t / a ore more reasonable. advance by 400 million t / a underground mining arrangements. annually to provide 200 million t of Kunming Steel's high-quality iron ore, copper to make it truly become the main vehicle for Queensland 3.3 Dahongshan Iron ore base construction, the main problem there is the implementation of construction funds. Since the mine will open, while keeping a larger scale, in the limited and Yunnan Kunming Iron and Steel raised the absence of sufficient financial resources, and actively introduce foreign investment is a good way to develop, should be promoted. even if such efforts fail, Yunnan and Kunming Iron and Steel should be determined to take various measures to raise the necessary funds to accelerate construction. 3.4 The large amount of underground development work required If you lose a few years of construction period of the preparatory work, organize the infrastructure put into building the power In 1996, 2,000 years ago, large scale Red Hill Iron is entirely possible.
