Abstract
Flotation is a complex multifaceted process that is widely used for the separation of finely ground minerals. The theory of froth flotation is complex and is not completely understood. This fact has been brought many monitoring challenges in a coal processing plant. To solve those challenges, it is important to understand the effect of different parameters on the fine particle separation, and control flotation performance for a particular system. This study is going to indicate the effect of various parameters (particle characteristics and hydrodynamic conditions) on coal flotation responses (flotation rate constant and recovery) by different modeling techniques. A comprehensive coal flotation database was prepared for the statistical and soft computing methods. Statistical factors were used for variable selections. Results were in a good agreement with recent theoretical flotation investigations. Computational models accurately can estimate flotation rate constant and coal recovery (correlation coefficient 0.85, and 0.99, respectively). According to the results, it can be concluded that the soft computing models can overcome the complexity of process and be used as an expert system to control, and optimize parameters of coal flotation process.

According to the flotation test results (Fig. 1), recovery of coal particles increased with the increasing of Sb
Summary
Global consumption of primary energy continues to grow. Especially coal demand has increased from 2013 China has started to import the heating coal. Coal is domestically the largest source of energy in America, and demands to generate electricity and to produce high grade coking coal have made the process of fine coal (-500 lm) reasonable. These facts have emphasized on the Electronic supplementary material The online version of this article (doi:10.1007/s40789-016-0147-9) contains supplementary material, which is available to authorized users. Flotation is a physicochemical separation method which is undoubtedly the most important and versatile mineral processing technique for the beneficiation of fine valuable particles (Wills 2006; Jena et al 2008; Abkhoshk et al 2010)
