Silica sand from Kandal province, Cambodia and Tapah Perak, Malaysia was grounded into an average micron size of and µm. Both sands were characterized by Xray fluorescence (XRF), Xray Diffraction, particle Size Analysis, Differential Thermal Analysis and Thermogravimetric Analysis (DTA/TGA). Malaysian silica sand was designated SDMTP and .
Gold is found in lode deposits, residual deposits, alluvial deposits, bench deposits, streambed deposits, ancient rivers, and flood layers. A lode deposit is a crack or fissure in hardrock that's full of gold. This is the original source of placer deposits. Residual deposits are pieces of ore that have eroded away from a lode.
