Abstract
The purpose of this research is to characterize amang from Rahman Hydraulic
Tin Sdn. Bhd and preconcentrate tin in amang. There were two different places of
samples available in this research several tests were implemented in this research such as
moisture content test, Loss of Ignition (LOI) test, Particle Size Distribution (PSD)
analysis, X-Ray Fluorescent (XRF) analysis, X-Ray Diffraction (XRD) analysis,
Scanning Electron Microscopy (SEM) analysis, Optical Microscopy, determination of
density and a simple ‘floatation’ concept process. From this research, quartz (SiO2),
pyrite (FeS2), arsenopyrite (AsFeS), sulphur trioxide (SO3) were found to be the highest
content among the other mineral in RHT Amang. Referred to the images of SEM,
cassiterite were found on interlock with other mineral. The largest quantity of mass of
the amang in range size 75-125 µm. Based on LOI test, both samples can be considered
to have quite high value of LOI which proved that RHT Amang have high volatile
substances such as sulphide mineral. Since the RHT Amang is fine for further process to
extract tin in amang, might best to use floatation method.
