Abstract (en)
[origin: WO2012000785A1] The invention relates to a method for the wet processing of materials, such as ores or similar materials, by means of a closed circuit grinding process in a container mill and the classification of the grinding stock heavy medium by at least one hydrocyclone that discharges into the feeding section of the mill. According to the invention, coarse grinding stock present at the underflow of the hydrocyclone reaches a screening device after the first cyclone classification in order to carry out a second classification, wherein fine grinding stock that has been filtered out is separated and only the remaining coarse grinding stock is added to the mill circuit, and said mill circuit is thereby relieved.
