In accordance with the present invention, it is an object to provide a method for preparing zinc carbonate from zinc ash using a urea solution. A series of heating and filtering steps are used to remove various contaminating metals and to precipitate the final basic zinc carbonate product.he method of the invention provides advantages over prior art methods of preparing zinc carbonate from zinc bearing flue dust. The present method provides for the use of urea to react with zinc at a temperature whereby ammonia and carbon dioxide are released.
