| Abstract Scope |
This study aims to the mitigation of a phosphate mining project impacts by finding a valorization solution for the 170 Mt of flotation residues forecasted to be produced in Sept-Îles, Quebec. A granulation process has been developed to transform the initial waste into valuable aggregates, which could be used as concrete or pavement components. Moreover, carbon dioxide has been used as a component of the granulation drum atmosphere. This allows to explore the possibility of processing the industrial residues with the exhaust gases of two adjacent industries, including a major aluminum refinery.
The presentation of the project will include all the experimental method, from the initial material characterization to the results concerning the compressing strength of the manufactured aggregates. Granulation tendencies and main influencing factors will be outlined, as well as an evaluation of the cost and of the greenhouse gases that could be emitted at an industrial scale. |
