dc.description.abstractIn this study, “The Effect of Milling Time, Stirring Speed and Ball Mill to Powder Ratio of Malaysian Tin Ore” has been carried out to characterize raw material and milled product of the tin ore sing XRD, XRF and SEM-EDX. Prior to experimental work, raw material and milled product was characterized using XRD, XRF and SEM-EDX. The experimental work is designed based on 2 3 + 3 factorial design with three central point. The three variables in the milling process were milling time (𝑋1), stirring speed (𝑋2), and ball mill to powder ratio. The investigation of main significant effect and interaction effect between variables were analysed using ANOVA Minitab 18. The effect of milling variable on elemental composition was estimated by XRF. Based on the statistical model generate from the ANOVA, it was found that milling time (𝑋1) has the most significant effect on the elemental composition followed by the stirring speed (𝑋2).The XRF result showed the presence of different aggregates of minerals and chemical composition that are Si, Al, Si, Fe, As, Mn, Mg, Na, Ti, P, Cu and Zn. XRD phase pattern showed that the other minerals such as cassiterite, hematite, magnetite, pyrite, arsenopyrite, rutile, stibnite and zircon are present in the XRD analysis. SEM-EDX showed the elemental composition present such as iron, calcium, sodium, aluminium, arsenic and silica, while SEM showed the morphological surface.en_US
