Abstract
A system and method for conversion of alkali metals, heavy metals, halogens, and sulfur into mineral products. The system includes a single reaction vessel. To begin the process, co-reactants such as lime and clay are mixed with waste feeds containing alkali metals, heavy metals, halogens, and sulfur. This mixture is then introduced into the reaction vessel. The reaction vessel is operated under reducing conditions. After the mineral products are allowed to form, they are collected from the reaction vessel.
