Ghosh, C and Pai, D R and Narasimham, B and Majumdar, K (1969) Benefication of low grade wolramite ore from Degana, Rajasthan. In: UNSPECIFIED.
WOLFRAMITE is one of the principal minerals containing tungsten and is considered as a strategic mineral because of its importance and short supply. It is a tungstate of iron and manganese (Fe, Mn) WO4 and generally occurs in prismatic or tabular crystals having a hardness of about 5 and a specific gravity ranging between 7.2 and 7.5. It is usually black in colour and has a good cleavage which causes it to fracture readily into thin flakes It is fairly magnetic. It usually contains 60'6%,', W03, though theoretically it should contain 76.5% WO3.
