| 中文摘要: |
| 贵州中部清镇、修文等地石炭系铝土矿底部的铁矿俗称为“清镇式铁矿”，与黔中铝土矿共同赋存于下石炭统九架炉组之中。本文在实际勘探工作及通过勘探阶段在钻孔副样中采集的铁矿进行可选性试验基础上，以同类型的清镇市猫场铝土矿红花寨、白浪坝矿段铝土矿共生的铁矿为研究对象，指出该类型铁矿矿石自然类型为赤铁矿和褐铁矿；工业类型为需选铁矿石；矿石矿物主要为赤铁矿，部分赤铁矿水化为针柱状褐铁矿；脉石矿物则以白云石和方解石为主。矿石中可供利用的主要元素是铁，造渣组分主要是硅、铝，其次为钙、镁等。试验结果表明，该矿采用一粗一精一扫的强磁选试验可获得铁精矿TFe含量5558%，回收率8011%的良好指标，精矿中各元素含量达到H55-Ⅰ类赤铁精矿质量要求，在当前市场条件下采用推荐工艺处理该矿可获利。结论对黔中铝土矿资源的综合勘查开发具有借鉴意义。 |
| 英文摘要: |
| In Qingzhen, Xiuwen of central Guizhou, the iron mine in the bottom of Carboniferous bauxite deposit is common called ‘Qingzhen style’ iron mine, associated in Jiujialu formation of the Lower Carboniferous with bauxite deposit of central Guizhou. In this paper, by actual exploration and electronmagnetic experiment of iron ore gathered in drill accessory sample in exploration period, the same type iron mine associated with bauxite in Honghuazhai section and Bailangba section of Maochang bauxite deposit in Qingzhen city is taken as an example, it points out that the natural type of this iron ore is hematite and limonite, the industrial type is smelted needed ore, the mineral ore is mainly hematite, some hydrate to be column limonite. The gangue mineral mainly are dolomite and calcite. The major useful element in the ore is iron, the slag component are silicon, bauxite, calcium, magnesium and so on. According to the experiment, it shows that the pure iron TFe content could be 55.58% by once corse, once well and once clean high intensity magnetic separation experiment, the recovery rate could be 80.11%. each element in the pure ore reach the quality requirement of H55-1 pure hematite ore. Under the present market condition, this mine will be profitable by invented process technique. It will has some guding significance for comprehensible exploration and development of bauxite deposit in the central Guizhou. |
