某地露天铁矿下部采区不同境界矿石性质差别较大，当不同境界矿石入选时，入选矿石的品位和可选性会发生较大的变化，造成生产指标波动，对生产产生影响。为稳定生产，对下部两个境界的矿石进行选矿试验研究，根据试验结果确定该采区不同境界矿石性质及可选性，使选厂根据不同境界矿石入选采取相应的操作，指导生产，确保生产指标稳定。%A mining area to the lower portion of the open iron ore properties vary greatly different realm,when different realm ore selected,selected ore grade and optional large changes will occur, resulting in the production index fluctuations have an impact on production.Stable production,mineral processing test research on the lower part of the realm of two ore,according to the test results to determine the nature of the ore mining area different realm and,optionally,making processing plant was selected to take appropriate action depending on the state of ore,guiding production,to ensure the production indicators of stability.
