The neutralization stage consists of adding lime or limestone to the weak acid stream, which contributes to the formation of white gypsum and red gypsum as complete neutralization by-products. Red gypsum is formed mainly of gypsum, as shown in Eq. 6.1 and iron hydroxides, as in Eq. 6.2 and is separated from the solution by filtration.
