Résumé
Rio Tinto's Aluminium division operates smelters in Canada, primarily in the Saguenay–Lac-Saint-Jean region in Quebec, where its entire aluminium production line generates two specific calcium sulphate (CaSO4) by-products. The aqua-catalysed hydrated lime (CHAC) is the by-product of the sulphur scrubber at the coke calciner plant, and the neutralised synthetic anhydrite (SA) is derived from the industrial processes of the chemical transformation of calcium fluoride into aluminium fluoride, which is used in the manufacture of electrolysis bath for aluminium production. Since 2015, several research projects have been developed at the Rio Tinto-Arvida Research and Development Center, in collaboration with local universities, to evaluate the potential of these by-products as a liming agent for various agroecosystems and as a certified calcium-rich fertiliser for lowbush blueberries, our regional flagship. The aim of this paper is to present the research and development programme that has led to the agricultural recycling of these two by-products.
