ABSTRACT:
A process for the recovery of bacitracin in the form of a zinc complex wherein the pH is raised to precipitate the zinc bacitracin complex. The zinc bacitracin complex is precipitated in the presence of ammonium ion which complexes the excess zinc and maintains it in solution, thereby preventing coprecipitation of zinc hydroxide.
