Experiment Study of Effects of Coal Slurry Properties on Particle Settling Velocity Based on SPSS Software

In order to explore the influence of coal slurry properties on particle settling velocity, orthogonal tests with four factors in five levels concerning coal slurry concentration, proportion of -45μm fine content, pH value and water hardness were conducted without consideration of interactions using SPSS 19.0 software with coal slurry suffering difficult to sediment problem from Jisan coal preparation plant on the basis of a clear knowledge of slime mineral composition there. Furthermore, an introduction of SPSS’s application in design and analysis of mineral processing experiment is made in this paper.
