Removal of quartz from iron ore was accomplished industrially via an anionic reverse flotation technique. However, in that kind of flotation, the interaction of the flotation reagents with the components of the feed sample makes the flotation a complicated system. Thus, the selection and optimization of regent dosages at various temperatures were performed using a uniform experimental design to estimate the optimum separation efficiency. Besides, the produced data as well as the reagent system were mathematically modeled at different flotation temperatures, and the graphical user interface GUI of MATLAB was conducted. The advantage of this procedure is that the user interface displayed in real-time can be conducted by adjusting the temperature at different values to automatically control the reagent system, besides predicting the concentrate yield, total iron grade, and total iron recovery.
通过阴离子反浮选技术，从铁矿石中去除石英在工业上已经实现。然而，在那种浮选过程中，浮选药剂与给料样品成分的相互作用使浮选成为一个复杂的系统。因此，使用均匀实验设计在不同温度下对药剂用量进行选择和优化，以估计最佳的分离效率。此外，在不同浮选温度下对所得到的数据以及试剂系统进行了数学建模，并利用 MATLAB 的图形用户界面（GUI）进行了操作。该过程的优点在于，可以通过调整不同温度的值来实时显示用户界面，从而自动控制试剂系统，同时还可以预测精矿产量、全铁品位和全铁回收率。
