La Mine de Siilinjärvi

Les phosphates sont essentiels à la création de solutions alimentaires et environnementales. Parlons de la mine de Siilinjärvi de Yara Suomi, l’une des plus grandes mines à ciel ouvert de Finlande.

Prenant son nom de la ville finlandaise voisine de Siilinjärvi, la mine de Siilinjärvi est la seule mine de phosphore en activité dans l’Union européenne. Elle est située au sommet du deuxième plus grand complexe de carbonatite de Finlande, après la formation de Sokli. Depuis 1979, elle produit un million de tonnes de concentré d’apatite par an. Des engrais et de l’acide phosphorique sont produits à partir de ce concentré. Plus de 10 millions de tonnes de minerai sont extraites chaque année, et la teneur moyenne en P2O5 dans l’alimentation du moulin est de 3,8 %. À l’heure actuelle, la mine devrait durer jusqu’en 2035.

Dans les concentrateurs, la flottation à l’écume est utilisée pour créer le concentré d’apatite. Le minerai de la mine est généralement composé de 10 % d’apatite, 20 % de carbonate de calcium et 65 % de phlogopite difficile à séparer. Occasionnellement, l’écume déborde et refuse de s’effondrer, ce qui entraîne des conditions de pompage instables. Dans ce cas, l’ajout d’un inducteur secondaire et d’une pale d’induction de flux à la roue de la pompe permet de pomper des boues à haut FVF sans bloquer l’œil de la roue. Cela réduit la perte de produit due au dégagement des CARS vers le réservoir d’aspiration et au débordement du puisard.
