Walter Weldon, a notable figure in the 19th century, is credited with developing the Weldon process in 1866. This revolutionary process aimed at the recovery of manganese dioxide for reuse in chlorine manufacture, with commercial operations commencing at the Gamble works in St. Helens in 1869. Weldon's innovative approach involved the development of a method to recycle waste manganese(II) chloride solution by treating it with lime, steam, and oxygen to produce calcium manganite(IV). This calcium manganite could then be used in the production of chlorine. The Weldon process, detailed in J.R. Partington's book "The Alkali Industry," marked a significant advancement in the manufacturing of chlorine at the time. Although the Weldon process was later superseded by the Deacon process and subsequently the Chloralkali process, its impact on the industry is indisputable. The contributions of Walter Weldon continue to be recognized and studied in the field of chemical processes.
