采用响应曲面法优化蓝晶石浮选试验
|
摘要
本文针对河北邢台卫鲁地区蓝晶石选矿流程中强磁选后的非磁性产品进行粗选试验研究。在单因素条件试验的基础上,根据Box-Behnken原理,建立了响应值精矿品位及精矿回收率与三个主要影响因素之间的回归方程,探索了最佳的药剂用量。在最佳浮选工艺条件下,即矿浆浓度25%,十二胺盐酸盐用量45 g/t,抑制剂淀粉用量380 g/t的条件下,预测精矿品位为39.46%,精矿回收率为66.53%。验证试验与预测值的相对误差均为0.02%,与模型预测值吻合度较高。证明了二者之间的高度相关性,说明该预测模型在本试验的研究范围内是有效、合理的。
Through the flotation experimental study of kyanite ore which is from Hebei xingtai WeiLu region,the kyanite ore comes from magnetic products of magnetic separation in the benefication process. Based on the condition of a series of single factor experiment. According to the principle of Box-Behnken, it established the regression equation between the response value on concentrate grade and three main influencing factors, by using the response surface methodology to further optimization of test conditions, to explore the best dosage of reagents, and select the optimal dosage of reagents for validation test. When the pulps inhibitor density was 25%,and the dosage of 12 amine hydrochloride was 45 g/t and the dosage of starch was 380 g/t,under the optimum leaching process conditions, through the test,the relative error of the test and prediction is0.02%,it achieved good technical index, which was high degree agreement with model prediction(39.46%,66.53%),and proved the high correlation between them, showed that the forecasting model within the scope of this experimental research was effective and reasonable.
