Abstract
PURPOSE: To convert cyanide-contng. solid waste into a harmless cake, by treating the waste with a steam autoclave in the presence of a calcium component and a silicate component.
CONSTITUTION: Cyanide-contng. solid waste is mixed with a calcium component, e.g. slaked lime, quick lime, limestone powder or the like, and a silicate component, e.g. silica sand, silica powder, diatom earth or the like. The amounts of addition are controlled so that the calcium component will exist in an amount of about 1W 50wt% based on CaO or calculated as CaO in dried cake, while the silicate component in an amount of about 1W50wt% based on SiO2. After the addition, the mixture is agitated, blended, and then charged into a steam autoclave, where it is heated, reacted and caked. The solid waste may be preliminarily dewatered, if necessary.
