The aim of this project is to
The project will be performed by laboratory experiments and can be divided in three main parts;
The overall goal of the project is to obtain results that can be the basis for the construction of a pilot plant, where Zn (and possibly other metals) can be extracted from fly ash in an environmentally and economically sustainable manner. A full scale plant for Zn recovery is under construction in Switzerland. However, there are several important differences between Sweden and Switzerland, which means that if a similar plant were built in Sweden it might not be economically viable. Thus we needs studies starting from the Swiss process but adapted to Swedish conditions to be able to develop effective and sustainable recovery methods.
