Abstract

Various morphological parameters that affect the flotation recovery of sphalerite were modelled and optimized using the response surface method (RSM). The effects of roughness value, shape factor, and collector concentration were investigated using the central composite full design method. The results were evaluated by analysis of variance. The optimum roughening time was found to be 25 minutes, the optimum roughness value was 2.9071 um, and the optimum collector concentration was 0.001 M. Using these values, a flotation recovery of 98.01% was obtained. Similarly, in shape factor studies, the optimum grinding time was 15 seconds, the optimum roundness value 0.7421, and the optimum collector concentration 0.0009 M, which resulted in a flotation recovery of 94.30%. The average error between the optimization results and the experimental results was estimated to be less than 6%, and the R2 values were greater than 90%. The study shows that RSM can be effectively applied in finding the economic optimum condition for obtaining maximum flotation recovery with minimum reagent consumption.

利用响应面法优化形状因子，研究对闪锌矿浮选回收率的影响

采用响应面法(RSM)对影响闪锌矿浮选回收率的各种形态参数进行了建模和优化。采用中心复合完全设计方法，研究了粗糙度值、形状因子和捕集剂浓度的影响。通过方差分析对结果进行评价。结果表明，最佳粗化时间为25 min，最佳粗化值为2.9071 um，最佳捕收剂浓度为0.001 m，可获得98.01%的浮选回收率。同样，在形状因子研究中，最佳磨矿时间为15 s，最佳圆度为0.7421，最佳捕收剂浓度为0.0009 M，浮选回收率为94.30%。估计优化结果与实验结果的平均误差小于6%，R2值大于90%。研究表明，RSM可以有效地用于寻找以最小药剂用量获得最大浮选回收率的经济最佳条件。
