为了探讨灰色理论模型应用于矿物浮选试验中的可行性,首先利用响应曲面法针对孔雀石浮选条件进行试验设计,选取硫化钠、异戊基黄药和硫酸铵三种药剂的用量为自变量,浮选回收率为因变量,采用CCD设计方案进行建模.结果表明,显著性大小由高到低依次为:异戊基黄药用量、硫酸铵用量、硫化钠用量.再在响应曲面法的数据基础上建立灰色理论模型,选取硫化钠、异戊基黄药、硫酸铵三种药剂用量为比较序列,孔雀石浮选回收率为参考序列进行关联度分析,分析结果表明,三种药剂用量同浮选回收率的关联度大小排序与响应曲面法分析显著性结果排序相一致.表明灰色理论模型可用于浮选试验结果分析是可以借鉴的.
The feasibility of Grey theory analysis in mineral flotation experiment was discyssed.A response surface methodology model was established for malachite flotation.The dosage of sodium sulphide,isoamyl xanthate and ammonium sulfate was chosed as independent variable and recovery as dependent variable by the designing scheme of CCD.The results show that significance from large to small are as isoamyl xanthate,ammonium sulfate and sodium sulphide.Grey theory model was established based on the data of Response Surface Methodology,The dosage of sodium sulphide,isoamyl xanthate and ammonium sulfate was chosed as comparison sequence and recovery of malachite fotation as reference sequence,The correlation degree analysis of three reagent dosage are in accordance with the Sorting of significant of Response surface method.The result indicate that Grey theory analysis can be applied to flotation experiment as a useful method to learn.
