  • Thorium processing | Britannica

    Thorium processing, preparation of the ore for use in various products. Thorium (Th) is a dense (11.7 grams per cubic centimetre) silvery metal that is softer than steel. It has a high melting temperature of approximately 1,750 °C (3,180 °F). Below about 1,360 °C (2,480 °F), the metal exists in ...

  • Mineral processing | metallurgy | Britannica

    Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.

  • Apatite - Wikipedia

    Apatite is occasionally found to contain significant amounts of rare-earth elements and can be used as an ore for those metals. This is preferable to traditional rare-earth ores such as monazite, as apatite is not very radioactive and does not pose an environmental hazard in mine tailings.However, apatite often contains uranium and its equally …
