What part of the world? If you're in America, then you will likely have to contact a certified hazardous materials company to satisfy EPA regulations.

The lime needs to be added slowly, as the reaction is exothermic. Continue until the pH reaches 7.

Calcium sulphate precipitates out of the solution, which has commercial uses and a value.
