Potensi deposit wolfram di Indonesia

Bangka island is one of the islands in Southeast Asian Tin Belt that makes Indonesia largest tin (Sn) producer world. The carrier wolframite a by product mineral (cassiterite). This study aims to presence and type wolfram-as deposits on island. research area was conducted eastern edge Klabat Granite Kepoh Village, Toboali District, South Bangka, at coordinates 106o 31' 58" BT, 2o 56' 56 " LS. result shows wolfram with grade veins reaching 8287 ppm. Wolfram identified as an associated mineralization system along rare earth metals (LTJ), molybdenum (Mo) platinum (Pt). results analytical studies (UV, XRF, ICP OES, mineragraphy) minerals show ores, concentrates, slag, floor crusts. are (Fe.Mn)WO4 scheelite (CaWO4) which characterized through differences properties such color, fluorosence, magnetic, specific gravity hardness values. obtained showed content 742 ppm ore also process, specifically slag II 1.02%. In addition, indicated furnace anode slime. countries owns needs continue extraction process so receive added value from its minerals.
