Abstract
A method for forming strong and durable pellets from dust collected from stack gases. The dust includes CaSO.sub.3, CaSO.sub.4 and unreacted CaD. A portion of water required for total hydration with the dust is blended in a mixer. The moistened powder is stored in a conditioning container wherein the moistened powder is chemically reacted and heated to form a hydroxide with the oxides in the powder. Water is added to the hydrates and the wetted hydrates are subjected to an intense second mixing. The wetted hydrates are then pelletized in a pelletizer.
