Zinc oxide production by French process, p. 4 - finishing.com
December 5, 2018. Mr. Shubham, Normally zinc oxide from zinc hydroxide is manufactured by Sodium hydrosulphite manufacturers as they generate large quantity of zinc hydroxide. When you reacted zinc chloride with NaOH, zinc hydroxide forms with NaCl salt, so you have to wash NaCl salt from the precipitate.
