A method is shown for producing food grade quicklime and hydrated lime. Raw limestone feed stock is calcined in a kiln to produce quicklime which is then slaked to produce hydrated lime product. The present invention involves the discovery that, by increasing the calcination temperature a selected amount, the concentration of fluoride in the quicklime can be dramatically reduced to a level ...
