flow of leaching process

US5250273A - Hydrometallurgical leaching process and , flow of leaching process ,A process and apparatus for leaching metal values from a particulate mineral ore containing metal values employs a fluidized bed of the particles; a leaching agent solution containing dissolved oxygen flows upwardly of the bed in a lower leaching zone, to an upper clarification zone; a velocity profile is maintained to promote settling of ,Leaching - Christian Brothers UniversityEffectively, this point pretends that there are mixers on either end of the leaching process, combining both the L and V flows into a single stream This is thus a fictitious value, and one coordinate must be negative.
