我矿改进磁选流程——将单一磁选流程补加精选作业,使铁精矿品位由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议的跃进计划指标(铁精矿品位65％、回收率90％)。同时由于铁精矿质量的提高使过滤效率增长了1.3～1.5倍,解决了因为设备能力不足,生产以来长期存在的精矿不能全部过滤的问题。使我矿附产的铁精矿为高炉提供了优质原料,大大降低钢铁的冶炼费用。
I mine to improve the magnetic separation process - a single magnetic separation process to add a selection of operations, the iron concentrate grade increased from 60% to 67%, a slight increase in recovery rate, a breakthrough in the national black mineral leap forward meeting Leap forward plan indicators (iron concentrate grade 65%, 90% recovery rate). At the same time as the quality of iron concentrate to improve the filtration efficiency of 1.3 to 1.5 times, to solve the lack of capacity because of the equipment, the production of long-term concentrate can not be all the problems of filtration. Iron ore concentrate attached to mine provided high-quality raw materials for blast furnace, greatly reducing the cost of smelting steel.
