Abstract
The purpose of this research is to characterize sample silica and to recover the valuable
minerals found in silica samples obtained from in Terengganu Silica Sand. There are six
methods of characterization were implemented in this research such as Particle Size
Distribution, Loss on Ignition, X-ray Fluorescence (XRF), Microscopic Study, Panning and
Magnetic Separation. From this study, corundum (Al₂Oɜ), silica (SiO₂), rutile (TiO₂), and
hematite (Fe₂Oɜ) were found in amang Terengganu Silica Sand. The size of the sample that
was chosen for this the research is the ranges from +600 µm to -212 µm. As the result, from
composition analysis, the composition of corundum was increase when the size of particle is
decrease. However, this sample is from the gangue mineral of silica, but there is still have a
higher amount of silica that are still present in the waste.
