摘要：
A method for producing a lightweight ceramic aggregate, particularly from coal ash, according to the invention is characterized in that the raw material mixture of the total moisture content preferably below 20% by weight consisting of power station ashes originating from combusting coal, or ashes from combusting coal in a mixture with biomass ash, or ashes from co-combusting biomass with coal and phosphogypsum in an amount of up to 50% by weight, taken from dumps and/or from direct dump from a power station or a heat and power station, the raw materials from the dumps preferably being heated up in winter by a mixture of atmospheric air and exhaust gases from the step of burning and sintering, with a content of non-burnt coal above 6% by weight, agglomeration promoting agents like silty non-organic materials, preferably bentonite, preferably in an amount of up to 4% by weight, clay preferably up to 6% by weight, organic waste materials like used paints and lacquers, after-fermentation sludge in an amount pref
