Decanter centrifuges for dewatering
TAILINGS slurries can have a major impact on the community living in the vicinity of mining activity, and also carry significant environmental risk. Calls for greater transparency are mounting from all stakeholders including the mining industry, investors and governments in mining countries around the world. Small miners to large mining conglomerates are conducting trials to characterise their tailings and assess which dewatering technologies are the most effective and efficient. Alfa Laval offers a cost-effective solution to dewatering tailings using mechanical separation by solid bowl decanter centrifuges, which enable mines to dispose of tailings solids as a solid cake and remove the risk of storing slurries in a tailings dam. Conventional methods like pressure filtration have limitations, particularly when processing fines,...
