[0002] The waste acid generated from the purification of smelting flue gas is generally neutralized with limestone emulsion to produce by-product gypsum slag (CaSO4﹒2H2O). The limestone emulsion is usually prepared by ball milling with a wet overflow ball mill. Limestone of 5 - 15 mm and water are continuously added to the ball mill, and after ball milling, a limestone emulsion with a particle size of about 200 meshes is obtained.
