production of white gypsum from sulfuric acid

Production of Gypsum from Clam Shells and Waste Acid

The exploitation of the natural rock form deposit of gypsum is on the increase, necessitating the need to find alternative and efficient sources of gypsum so as to sustain all the industries dependent on gypsum as raw material. This work investigates the production of gypsum from clamshells and waste sulphuric acid from endoflife car batteries.
