摘　　要：本试验对某铜镍硫化矿镍品位分别为0.97%、0.80%、0.66%、0.53%、0.42%、0.17%的六批原矿进行了不同精矿品位的闭路试验,找出了精矿品位和回收率二者之间的一元线性关系,并建立了二者之间的线性回归方程,为生产企业在不同经济时期合理边界品位的圈定提供了依据。In this experiment,six batches of nickel sulfide ore with grades of 0.97%,0.80%,0.66%,0.53%,0.42%,and 0.17%respectively were subjected to closed circuit tests of different concentrate grades,and the unitary linear relationship between concentrate grade and recovery rate was found.The linear regression equation between the two is established,which provides a basis for defining the appropriate cut-off grade of production in different economic periods.

关 键 词：贫矿 品位 回收率 回归方程
