Abstract
A method of desulfurizing exhaust emissions which comprises pulverizing slag from a blast furnace, converter, open-hearth furnace or the like which is composed principally of Ca.sub.2 Al.sub.2 SiO.sub.7, suspending the resulting minute particles in water, and bringing the aqueous suspension of pulverized slag into contact with the exhaust that contains sulfur dioxide and oxygen, while supplying the slag at a rate to keep the pH of the suspension within a range of 1.5 to 4.0 and thereby to remove the sulfur dioxide from the exhaust.
