In the Isotherm\u00ae process, for each heavy metal, a fraction go in the fumes and the remaining fraction go in the slag; the fraction that goes in the fumes depends on the metal; several heavy metals go almost totally to the slag, others are divided between the two, while few others (mercury) go almost totally into the fumes. The fraction in the slag remains inert in the vitreous matrix and in no way compromises its industrial use; the part that goes into the fumes is treated in an appropriate column, provided for in the fumes treating section, where the remaining heavy metals are separated out with a process, patented by Itea, applicable to the entire heavy metal spectrum, including those present as nano-particles.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The fumes produced in \u201cflameless\u201d combustion are very pure, and consist essentially of CO2 and water vapour;
