  1. Dear Ms.Mariola
    We are the Mines owner of Barite and Hematite in Pakistan.
    We would like to make Barium Carbonate from our Barite.
    Please guide us.

    • Dear M.Afzal.

      Thank you for your interest. If you need mineralogical assessment of your barite and hematite – particularly looking at liberation, associations, texture, grain size or overall petrography then we would be happy to assist. However, we are not in a position to advise you on the preparation of barium carbonate from barite. For that, it would be best to contact a different company, (e.g. Wardell-Armstrong).

      Kind regards,
