  • Beneficiation of tungsten ores in India A review

    Tungsten is a strategic metal for India and almost the entire requirement is met by imports. Extensive search for tungsten in recent years has led to the discovery of several deposits. However almost all these are of low grade compared to world resources. Techno-economic exploitation of these deposits depends to a great extent on the development of suitable beneficiation technology within
