Barium Mining
Barium mining. Barium is an abundant alkaline earth metal found on earth. It is mostly extracted from its major sulfate ore 'Baryte or Barite'. Mining: The barium's chief ore barite is mined from the surface by open pit mining method. The presence of barite is first confirmed by initial analyzing process. The distribution of the ores also ...Web
