| 摘 要： | 土壤样品中对有用元素离子有较强吸附能力的非晶质铁锰氧化物在还原条件下高温（８００℃±）加热可能转化为磁性增强了的晶质铁锰氧化物。经磁分选分离出磁性较强部分并测试其中的有用元素含量可获得被运积物覆盖的找矿信息。通过实验取得了室内样品处理中适宜的粒度和加热温度的有用数据以及合理的磁分选流程，在已知矿区和未知区的试验均取得了明显效果。

| Abstract: | Active ions including ore-- foaling ions can be adsorbed by noncrystal Fe-Mn chides and wad heated, theSeoxides can become cristal chides with high magnetism under the reductive condition. The magnetic sepefation Of soil samples andmeasuring of their useful elements can provide some information related to buried ore deceits. In our exhoment, some data Ofgrain size of samples, heating temperature and reasonable procedure of magnetic seperation were obtained and obvious effects weremade in the testing on given and uncertain ore field. |
