Abstract: The invention relates to a method for processing waste incineration ashes (A), in particular domestic waste incineration ashes (HMVA), in which the ashes are classified into a plurality of fractions of different grain size distributions in a processing plant (11) separated from the actual waste incineration process. The ashes (A) are classified exclusively using a wet classification process in the processing plant (11), only wet classification processes that are gentle to the grains being used, and the wet classification process is performed in such a way that all of the ashes (A) are classified into at least one fine fraction (I) loaded with harmful substances and at least one coarse fraction (II, III) that contains only a small amount of harmful substances or no harmful substances at all.

Abstract: The invention relates to a method for processing waste incineration ashes, in particular domestic waste incineration ashes, in which a process for classifying the ashes and a process for recovering phosphates from the ashes are combined. In said method, the ashes are subjected to a wet classification process during which the ashes are mixed with a liquid, and the ashes are treated with an acidic aqueous solution to redissolve the phosphates, whereupon the phosphates contained in the solution are isolated. The liquid with which the ashes are mixed during the wet classification process is the acidic aqueous solution with which the ashes are treated to redissolve the phosphates.

Abstract: A method and apparatus for producing thin superconductor film of high temperature oxide type ceramic superconductors by cathodic sputtering and in which the highest possible oxygen partial pressure is utilized in the space between the cathode and the substrate. Ionizing radiation can be introduced into the space as well.
