Main Equipment Used For Iron Ore Tailings

Main equipment used for iron ore tailings

With the rapid development of the iron and steel industry, the proportion of iron ore tailings in the industrial solid waste is also growing. According to incomplete statistics, China discovered more than 150 kinds of mineral development to the establishment of more than 8000 mines, the cumulative production of tailings to 5.97 billion tons, which stockpiles of iron ore tailings accounts for all tailings stockpiles total / 3%. Tailings or valuable elements recycling are the main and preferred one of the measures to utilization, including the old tailings re-election and newly generated tailings re-election. Tailings can reduce the tailings dam construction and maintenance costs, saving the crushing, mining, transportation and other costs, but also to save the greater investment in equipment and new technology developed, so more and more attention.

Iron tailings waste emissions in the concentrator in the specific economic and technological conditions, crushers (crushing machine) and Mill (grinding machine) will be finely ground ore, select the "useful components", that is, ore elected concentrate the remaining solid waste. It is a composite of mineral raw materials in addition to containing exceptionally small amount of metal group, its main mineral component of the gangue minerals such as quartz, pyroxene, feldspar, garnet, amphibole and its alteration mineral. China's iron ore resources embedded in the cloth, fine grain size, which normally takes Sec crusher and mill grinding, a small number of three grinding, sorting, so in addition to the pre-selected to throw part of the coarse tailings, most of the dressing discharge stockpiling of tailings particle size smaller general tailings particle size
