在确立磷块岩矿石中化学组分与矿物组分间的数量关系,并对大量选矿试验结果的主要化学组分分配率进行统计分析的基础上,制定了预测精矿产率和主要化学组分的计算公式。根据不同磷肥产品对磷矿石的质量要求,制定了矿石产品方案和选矿方法选择的框图,从而提供了一套完整的磷块岩矿石选矿评价预测技术。
Based on the quantitative relationship between the chemical components and the mineral components in the phosphorite ore and the statistical analysis of the main chemical component distribution rates of a large number of ore dressing test results, the prediction of the yield of the concentrate and the main chemical components The formula. According to the phosphate fertilizer quality requirements of different phosphate fertilizer products, a scheme diagram of ore product scheme and beneficiation method is drawn up, so as to provide a complete set of phosphate ore rock ore beneficiation evaluation and forecasting technology.
