通过分批浮选试验和大量的小浮沉试验，研究了不同密度级煤泥浮选动力学模型，以及浮选剂添加量对煤泥浮选速率的影响关系，得出了煤泥浮选速率常数与煤泥密度和捕收剂用量及起泡剂用量之间的数学模型。并利用了不同密度级的浮选速率常数对实际浮选生产结果进行了预测。 Through the batch flotation test and a large number of small floatation experiments, the kinetic models of slime flotation at different densities and the relationship between the flotation agent dosage and flotation rate of slime were studied. The flotation rate A mathematical model between the constants and the density of slime, the amount of collector and the amount of foaming agent. The flotation rate constants with different densities were used to predict the actual flotation production results.
