摘要
利用现象学理论和数学理论建立的沉降过程数学模型和偏微分方程数值方法,对磁选工艺和浮选工艺的尾矿之絮凝沉降过程进行数值模拟,并按照实际絮凝沉降工艺过程进行试验。通过分析比较沉降试验数据与模拟数据,证明所采用的数学模型能够正确描述具有絮凝反应的工业实际沉降过程,可作为工业沉降工艺设计及沉降设备选型设计的理论依据。
Based on the mathematical model of settling process and numerical method of partial differential equation established by phenomenological theory and mathematical theory,the numerical simulation for flocculation settling process of tailings with flotation technology and magnetic separation technology is carried out,and its test is carried out according to practical flocculating settling process.By analyzing and comparing the test data and simulation data,it proves that the used mathematical model can correctly describes the industrial practical settling process with flocculating reaction,which could be used as theoretical basis for the design of industrial settling technology and the type selection of settling equipment.
