猫场矿区首采矿段储量大、品位高,可作为新建大型氧化铝厂或扩建已有氧化铝厂的原料基地。矿床直顶不稳固、含硫高、易崩落大幅度贫化采出矿石,因此要研究超前切顶房柱法的适用性。基本的对比分析表明,混采直顶经选矿处理后向氧化铝厂供精矿方案也有一些显著优点,有必要开展进一进的工作,为此应及早开始並尽早完成各阶段的选矿试验,以及与提高综合效益有关的试验硷研究。
The first mining section of Cathay Field has a large reserves and high grade, which can be used as a raw material base for newly-built large-scale alumina plants or expansion of existing alumina plants. The deposit is not stable straight top, high sulfur content, easy to caving greatly depleted ore mining, so to study the feasibility of the pre-cut roof method. The basic comparative analysis shows that there is also some significant advantages for concentrating the top-beneficiation concentrate to the alumina plant after beneficiation, and it is necessary to carry out further work. Therefore, the beneficiation trial should be started as early as possible and completed as early as possible, As well as research on the experimental base related to improving the overall benefits.
