With EMEW, the electrolyte is circulated past the anode and cathode at a higher flow rate, allowing for improvements in efficiency and recovery.Slide3: The main application of the EMEW cell is the recovery of high purity metals from a wide range of metal-bearing solutions, particularly those with relatively low metal concentrations and/or complex solution chemistries. As such, the EMEW cell will have an expanding application in the abatement of hazardous waste streams such as acid mine drainage, bleed streams from primary metal recovery processes, recycling of secondary materials, etc. Slide4: Plating Type Cell- Used with high concentrated solutions and metals that plate. Powder Type Cell- Used for low concentrated solutions or metals that form crystalline powders. There Are Two Types Of EMEW CellsSlide5: EMEW Plating Type Cell The end caps are made of PVC and are designed to direct the flow of electrolyte, support the anode and allow harvesting of the plated metal.Slide6: (-) (+) EMEW Plating Type Cell Electrical current is applied through bus bars attached in series from the anode to either the metal body or to a titanium contact inside the body of the next EMEW. Bus BarsSlide7: EMEW Plating Type Cell A Starter Sheet, usually made of stainless steel, is slid down inside the body of the EMEW. The metal being recovered is plated onto this removable starter sheet.Slide8: Cut Away of Plating Type EMEW CellsSlide9: Electrolyte is pumped through the cell from the bottom. Power is Applied Body of the EMEW is the Cathode (-) (+) Off Gases Collect At The Top And Vent Through The Gas Line. How A Plating Cell WorksSlide10: Electrolyte Flow Through a Bank of 10 EMEW Plating Cells. Power from the rectifiers will not turn on until flow is verified. Off Gases can be either collected at the end of the bank or mixed with the electrolyte and separated at the feed tank.Slide11: Harvesting Plating Type EMEW Cells The Cells Are Flushed With Water. Each Cell’s Top Is Removed and The Metal Harvested From Each Cell Still Attached to the Starter Sheet.Slide12: Copper being harvested from 150mm EMEW® plate pilot plantSlide13: Harvesting Copper At AsarcoSlide14: Solution Is Transferred To A Batch Tank and Then Circulated Through the EMEW Cells. Pump Started A Typical EMEW Batch Type Circuit EMEW Cell Banks In Parallel. Solution Is Circulated Until The Metal Reaches a Set Depletion Point.Slide15: The cell ends are designed to facilitate the removal of the metal powder, Electrolyte flow to and away from each cell is supplied by a header system instead of in series and The metal powder is separated from the electrolyte by a filtering system. A powder cell is similar to a plating cell except:Slide16: Powder CellsSlide17: EMEW Advantages Over Standard Technologies High Electrowin Efficiency, High Current Densities, Recovery of Metal From Low Grade and Waste Solutions, Operates Over Wide Range of Concentrations, Operates in Various Electrolyte Solutions, Including Acid, Caustic, Cyanide and Chlorides, System Is Completely Closed, Allowing Capture of Noxious or Toxic off Gases and Mists, Modular Design, suitable for small scale applications, Low Capital Cost And Expansion Flexibility.Slide18: Metals Proven Applicable to EMEW Technology Copper Silver Gold Zinc Nickel Palladium Cobalt Tin Antimony Slide19: Promising EMEW Applications Environmental Recovery of Saleable Metal From: Contaminated Streams Pond Waters Industrial Waste Streams Leachable Metals in Soils. Industrial Removal/recovery of Metals From: Wash Waters Leachable Scrap Catalysts Etching Solutions Chloride Solutions Cyanide Solutions Slide20: Copper recovery plant at Radio Hill nickel mine in Western Australia, utilizing EMEW® 200mm powder cellsSlide21: EMEW® plant treating acid mine drainage at Grasberg copper-gold mine in Irian JayaSlide22: Forty Cell Copper Recovery Circuit At Asarco - Amarillo Copper RefinerySlide23: Harvested Copper From Asarco’s 40 Cell EMEW Circuit You do not have the permission to view this presentation.
