Hydrometallurgical solubilizer with selective electroplating mechanism
Abstract
Abstract A CONTAINER FOR CONDUCTIVE SOLUTION IS DIVIDED INTO A FIRST COMPARTMENT AND A SECOND COMPARTMENT BY AN INERT PERMEABLE BARRIER. THE SOLUTION IS ELECTROCHEMICALLY ACTIVATED TO PRODUCE AND CONTROL THE PH OF AN ACIDIC SOLUTION WITHIN THE FIRST COMPARTMENT AND A BASIC SOLUTION WITHIN THE SECOND COMPARTMENT. PULVERIZED ORE IS DEPOSITED WITHIN THE ACIDIC COMPARTMENT AND REACTS THEREIN WITH THE ACID TO SOLUBILIZED THE METALS AND MOSTE METAL COMPOUNDS CONTAINED WITHIN THE ORE. THE SOLUBILIZED METAL COMPOUNDS ARE CARRIED THROUGH THE BARRIER INTO THE BASIC COMPARTMENT BY IONIC FLOW AND FLUID FLOW. A PLURAITY OD METAL PLATES ARE LOCATED WITHIN THE BASIC CHAMBER FOR PLATING OUT A SELECTED ONE OF THE METALS AS DETERMINED BY THE CHEMICAL COMPOSITION OF THE SOLUTION AND THE VOLTAGE DROP ACROSS EACH OF THE PLATES.
