Tailing deposits at ex-tin mining area in Bangka and Belitung Island has a large number of economical
residual minerals. This study is to identify tailing characteristic and its potential mineralogy and
elements based on shallow hand boring (Auger) samples, along stream line in west part of Sambung
Giri Hill. Every coordinate sample plotted on base map. Loboratory analisys using Strereo
Mikroscope for identify minerals characteristics, and geochemical analysis using XRF for identification
the presence of elements. The tailing deposits has laterally grain size gradation to down stream,
composed above 94% sand fraction, and small amount of shale and granule fraction. Quartz mineral
presence more then 90%, followed by iron oxide (hematite), clay, zircon, cassiterite, ilmenite, monazite
and tourmaline minerals, showed low consistency in lateral spatial exept quartz, with its Rare Earth
Elementh (REE) composition is Cerium (Ce), Lanthanum (La), Yttrium (Y), Neodymium (Nd) and
Samarium (Sm).
