Determination of mass attenuation coefficients for several natural minerals in Malaysia

Mass attenuation coefficient (µm) is an important parameter in both fundamental and applied mineral studies. The purpose of this study is to determine the values of mass attenuation coefficients of several natural minerals from various mining areas in Malaysia. Four types of minerals were chosen whi...

description Mass attenuation coefficient (µm) is an important parameter in both fundamental and applied mineral studies. The purpose of this study is to determine the values of mass attenuation coefficients of several natural minerals from various mining areas in Malaysia. Four types of minerals were chosen which are hematite, tin ore, xenotime and monazite. The samples were prepared in pallet form by mixing 7g of each sample with 3g of wax. The dimension of the pallet was 3mm in thickness and 40 mm in diameter. The element compositions of the samples were determined by using X-ray fluorescence (XRF) spectroscopy.
