percolation[pər·kə′lā·shən] (computer science) The transfer of needed data back from secondary storage devices to main storage. (hydrology) Gravity flow of groundwater through the pore spaces in rock or soil. (mining engineering) Gentle movement of a solvent through an ore bed in order to extract a mineral. (science and technology) Slow movement of a liquid through a porous material. Percolation a method used to leach ores in a fixed bed, mainly, copper oxides and gold ores; leaching by this method is called percolation leaching. The process is carried out in a percolator tank. The pulverized ore is uniformly loaded onto the tank’s false bottom, which is a filtering device. The leaching solution is introduced either from beneath the false bottom, a process called upward leaching, or onto the surface of the load, a process called downward leaching; accordingly, the solution is collected either above or below the false bottom. percolationThe downward movement of water into soil.percolation
