摘要： Method of treating minerals containing insoluble impurities to form sludge, the kind of treatment in which the mineral is agitated in a liquid such as water or an aqueous solution to effect washing in a known manner, characterized in that the muddy solution and obtained is sent to the first cyclone of a series of n cyclone is withdrawn at the tip of each of the N-1 first cyclone slurry that is sent to the next cyclone, and in the top of the n cyclones overflow, the muddy liquid from the first cyclone is sent to apparatus for clarification, the second cyclone, is divided into two fractions of which one returns to the first cyclone and the other washing and, from the following N-2 cyclones, is sent to the cyclone preceding that from which it comes, being the nth cyclone of the series fed by the clarified water and giving a thick suspension solution practically cleared of sludge and of extremely fine mineral particles.
