我矿改进磁选流程——将单一磁选流程补加精选作业,使鉄精矿品位由60％提高到67％左右,回收率稍有上升,这一指标突破了全国黑色选矿跃进会議的跃进計划指标(鉄精矿品位65％、回收率90％)。同时由于鉄精矿质量的提高使过滤效率增长了1.3～1.5倍,解决了因为設备能力不足,生产以来长期存在的精矿不能全部过滤的問題。使我矿附产的鉄精矿为高爐提供了优質原料,大大降低鋼铁的冶炼費用。
I mine to improve the magnetic separation process - a single magnetic separation process to add a selection of operations, the concentrate grade 由 improved from 60% to 67%, a slight increase in recovery rate, a breakthrough in the national black mineral leap forward meeting Leap forward plan indicators (鉄 concentrate grade 65%, 90% recovery rate). At the same time as the quality of 鉄 concentrate to improve the filtration efficiency of 1.3 to 1.5 times, to solve the lack of capacity because of equipment, production of long-standing concentrate can not be all the problems of filtration. The 附 concentrate that I attached to the mine provided high-quality raw materials for the blast furnace, greatly reducing the smelting costs of the steel.
