Abstract
Four types of samples from Selinsing and Buffalo Reef shows mineralogy from the area are mostly contain of minerals arsenopyrite, pyrite, sphalerite and chalcopyrite. There is also gold can be found in this area if further research and study are made. The mineral identification samples of low grade unleachable, low grade leachable, high grade leachable and Buffalo Reef are studied by the sieve size analysis, loss on ignition, elemental composition (by XRF), phase identification (by XRD), morphological study (by SEM/EDX and polarizing microscope), and mineral liberation by the imageJ software. From these identification, about 50% (sieve size analysis data) of these samples are contain the mineral arsenopyrite, pyrite, sphalerite and chalcopyrite (XRD, XRF, SEM). The quantitative data regarding the area and mean of the particle size at 2.36mm of each sample are quantify using the software of imageJ.
