Primary Uses or Exposures: Cobalt sulfate is used in the electroplating and electrochemical industries; as a drier for lithographic inks, varnishes, paints, and linoleum; in storage batteries; and as a coloring agent in ceramics, enamels, glazes, and porcelain. In addition, cobalt sulfate has been used in animal feeds as a mineral supplement and has been used on pastures where the forage is cobalt deficient to provide enough cobalt for ruminants (e.g., cattle, sheep, or goats) to produce vitamin B 12. Past uses include addition to beers to improve the stability of the foam and to improve blood values (hematocrit, hemoglobin, and erythrocyte levels) in people with forms of anemia not responsive to other treatments.
