KEFID is a professional manufacturer of mineral processing equipment , production of mineral production line equipment: molybdenum ore dressing equipment , lead-zinc ore processing equipment, magnetite beneficiation equipment, copper processing equipment , limonite processing equipment , gold ore processing equipment, steel slag iron equipment , sand iron equipment , hematite mineral processing equipment.

With the rapid development of the steel industry , the proportion of iron ore tailings in the share of industrial solid waste is also growing . Evolving global mineral resources , mining efforts are constantly increasing, the cumulative production of more and more out of the tailings , the tailings are not even the correct use , greatly reducing the exploitation of those economic benefits. Tailings or recycling of valuable elements is one of the measures the overall utilization of the main tailings and preferred , including the use of old tailings re -election , re-election of new generating tailings . Tailings dams and tailings dams can reduce maintenance costs , saving broken mill, mining, transportation and other costs, but also saving equipment and greater investment in new technology developed , so more and more attention .

Iron concentrator tailings are under specific economic and technical conditions, with crusher and mill the ore milled , select " useful components " after the waste emissions , which is elected by the ore concentrate remaining solid waste. It is a composite of mineral raw materials , in addition to containing a small amount of metal components, the main mineral component is gangue minerals , such as quartz , pyroxene , feldspar , garnet, amphibole and alteration minerals. Dissemination size of China's iron ore resources thin , generally subject to Sec crusher and grinding mill , a few three sections of grinding , sorting , so in addition to a preselected portion of the coarse tailings thrown out , most of the discharge and beneficiation stockpiling of fine-grained tailings , tailings particle size is generally <0.074mm accounted for 50 % to 70 %, only coarser tailings along the Yangtze River . According to differences in particle size of tailings , mine tailings recycling and processing of investment yield , etc. , KEFID offers many models of jaw crusher , vertical roller mill , super pressure trapezium mill , ultrafine mill to strengthen the full composition grinding process , according to the actual situation to select different combinations of equipment , iron tailings re- grinding , post-treatment process to achieve a certain degree of preparation of fine glass-ceramic , develop high-performance , low-cost high-end architectural or industrial corrosion resistant material damage improve the tailings product technology content and added value . With the continuous development of mineral resources, the tailings produced not only takes up a lot of land and pollute the environment, tailing recovery equipment and systems engineering continuous improvement, some of China's mining enterprises from improving economic efficiency considerations, has completed a number of iron ore tailings recycling options plant, tailings finishing , production of building decoration materials with high added value , and achieved significant economic benefits. Tailings will be the most extensive use of the comprehensive utilization of mineral range in the 21st century , the areas of greatest potential, will be the first to use the new resource people .
