At present, the battery industry makes leady oxide by either the ballmill or the Bartonpot process. It is difficult to conclude which of the two methods gives the best leady oxide. Each type of leady oxide has its champions but, in general, ballmill and Bartonpot product both make effective automotive batteries.

Lead dust can become airborne due to improper air flow or exhaust ventilation, which results in "puffing" of lead oxide at the mill inlet. Exposure may occur from handling lead pigs while loading the mill pots or the ball mill. Lead oxide dust may spill or leak from trunnion seals, bearing seals, conveying systems, and transfer points.

Barton pot: A fine stream of molten lead is inserted into a heated vessel. Each droplet reacts with the air to form an oxide layer, giving 70 85% lead oxide. Ball milling: Pieces of lead are put into a rotary mechanical mill, forming fine lead flakes, which are then oxidised in air and removed. This also gives 75 80% lead oxide.
