As part of the experimental studies carried out in the Department of Civil, Environmental Engineering and Architecture of the University of Cagliari, to identify the best techniques for recovering of combustible materials, contained in the waste resulting from the dismantling of the anodes of spent electrolytic cells used in the production of primary aluminium, to be concentrated by flotation, work was first carried out to reduce the size of the waste, in order to give it a particle size that would allow it to be ...

This paper presents the results of laboratory processing tests conducted to explore the potential for beneficiation of a wollastonite mineral (calcium metasilicate, CaSiO3). The ore studied comes from a mineralized body located in the southern part of Sardinia (Italy), which has been studied in the past with geological surveys and sampling. In the investigated area the mineralization was very irregular. The encasing rocks consist of schist and the mineralized body is composed of wollastonite associated with limest...
