Claim:
1. A method of processing incineration byproduct to obtain particles of unburned material, aggregate sand and ash, the process comprising the steps of: (a) receiving incineration byproduct and passing the incineration byproduct through a screen and separating particles having a dimension greater than approximately three inches from the incineration byproduct; (b) transferring the incineration byproduct to a wash plant equipped to hold water and the incineration byproduct; (c) mixing water with the incineration byproduct in the wash plant; (d) separating additional particles from the incineration byproduct in the wash plant, the additional particles having a dimension greater than approximately six mesh; (e) discharging the additional particles from the wash plant; (f) transferring incineration byproduct mixed with water from the wash plant to a thickener and separating ash from the water in the thickener with pH adjustment, coagulant and flocculant as ash sludge discharged from the thickener, and (g) dewatering the ash sludge discharged from the thickener to produce ash cake.
