| 摘要 | A method and apparatus for separating discrete solid articles according to their density is described. A fluid is placed in a vessel, and discrete solid articles having various densities are placed therein. The density of the fluid is altered to a value which will cause separation of the solid articles due to differences in buoyancy. The density of the fluid separating medium is preferably altered by injection of small gas bubbles or other fluid substances having a density differing from the first fluid placed in the vessel. | ||||||
