There are numerous technologies to extract magnesium from tailings piles coming from asbestos mining. In the invention we have found that silica which is a component of the asbestos fibers with magnesium oxide can be extracted with magnesium in combining extraction of the asbestos fibers by flotation (wet-milling technologies), the treatment of the water-soaked fibers with an acid and, after reaction the separation of the solid silica from the magnesium salt solution which can then process. The silica shows a great surface area (400 -450 m2/g) which makes it a valuable product with many industrial applications. The extraction of these two products gives a good profitability to this new tailings processing technology.

De nombreuses technologies permettent d'extraire le magnésium contenu dans les amas de résidus provenant de l'extraction de l'amiante. Dans la présente invention, on a montré que la silice, un constituant des fibres d'amiante avec l'oxyde de magnésium, peut être extraite avec le magnésium en combinant l'extraction des fibres d'amiante par flottation (broyage liquide), le traitement des fibres imbibées d'eau par un acide et, après réaction, la séparation de la silice solide de la solution de sel de magnésium, qui peut ensuite être traitée. La silice présente une grande surface de contact (400-450 m2/g), ce qui en fait un produit utile à de nombreuses applications industrielles. L'extraction de ces deux produits confère une bonne rentabilité à cette nouvelle technologie de traitement des résidus.
