Re: Gypsum Production - Page 2 of 2

Jul 01, 2010 · there could be a temporary opportunity for cheap sulfuric acid. However, before the drop in price, the typical cost was 450 /ton(H2SO4). Since 0.57 tons of H2SO4 are needed to produce 1 ton of gypsum, this would imply a cost of 250 /ton(gypsum) only for the purchase of sulfuric acid. I wonder what would be the processing cost!
