Abstract: In a method and apparatus for removing water from sludge the sludge is introduced into an intermediate chamber from which it is fed into at least one sludge chamber having a filter surface. A hydrostatic pressure is built up in the sludge chamber to remove the water. The sludge chamber is then opened and the filter surface moved out of the sludge chamber to remove the filter cake. The hydrostatic pressure is generated by the sludge being transferred out of the intermediate container, after the continuous feed of sludge thereto has been cut off, by positive displacement of the volume of sludge from the intermediate container into the sludge chamber. The feed of sludge into the sludge chamber may occur simultaneously at a plurality of points from a corresponding number of intermediate containers.

Abstract: A method for leaching gold and/or silver out or other precious metal containing substance using cyanide-containing leaching solutions and adding an aqueous H.sub.2 O.sub.2 solution to accelerate leaching. The total amount of the hydrogen-peroxide solution required for leaching is fed into the leaching slurry at the beginning of leaching. The amount of the H.sub.2 O.sub.2 solution is determined in that the H.sub.2 O.sub.2 is added in a 0.6 to 2.5-fold stoichiometric ratio to the cyanide concentration of the leaching slurry. The pH value of the leaching slurry is set and maintained at between 7 and 10 or between 11 and 13.

Abstract: An improved water removal in a filter press used in sludge treatment processes, typically in a sewage plant, is provided through the addition of a pretreatment stage where water is removed to an appreciable extent. The filter press pretreatment system is based upon continuously circulating filter pockets into which flocculant-treated sludge has been added, a significant amount of the water from the thus clarified sludge being removed through the combination of the use of this pretreatment and in this pretreatment using filter pockets of variable volume.

Abstract: A filter apparatus comprising a gravitional extraction section 1 and a high pressure section 3. In the high pressure section 3 there is a rotatable drum 35 around which a pair of filter bands 4,5 on carrier belts 6,7 are advanced with means for applying pressure to the belts to squeeze the bands and belts together to expel water from the sludge 13 through open-topped channels formed in the carrier belts. An intermediate section 2 for applying medium pressure to the sludge may be provided and the bands and belts are continuous. Various special features like cleaning, different pressure loading systems, and driving means and other modifications are described but the principle is to progressively increase the pressure by advancing the sludge between the belt and carrier assembly and to arrange for the water expelled to be diverted through the channels 8,9 in the carrier belts with no frictional drag between the respective bands and belts as they advance at the same speed.

Abstract: Method for the liquid solid separation of material mixtures and suspensions in which the material mixture under pressure is fed into a closed chamber having at least one filter surface and a hydrostatic pressure is generated within said chamber for separating the liquid phase. After separating the liquid phase the chamber is opened and the filter surface together with the filter cake is removed from said chamber. The material mixture firstly is treated by the means of hydrostatic pressure of about up to 0.2 bar, wherein 80 to 90% of the fed volume is removed as filtrate. Thereafter the concentrated remaining volume is drawn off and is further treated in the closed chamber with a pressure of up to 5 bar. By reducing the volume of the chamber finally with a pressure of up to 50 bar the remaining filtrate is separated.
