A comparison of barton-pot and ball-mill processes for making leady oxide

There are two principal methods of making leady oxide for lead/acid batteries. These are: (i) the Barton-pot process, which utilizes the oxidation of molten lead; (ii) the ball-mill process, which employs the oxidation of solid lead. Several conflicting claims have been made for the advantages of the one process over the other, and vice versa. A comparison is made here by using information obtained from the Linklater type of Barton pot and a European type of ball-mill.
