Gold Refining by Electrolysis Process

gold_refining_plant

ALLOY BATCH CHARGE: 6-12+ Kg ALLOY MAXIMUM PER CYCLE


WORKING CYCLE TIME IN 24 hours = 3 BATCHES


PURITY CAN BE OBTAINED: FROM 999,0/5 TO 999,9/1000


This refining plant is used to obtain gold with purity of 999,9 ‰(thousandths)using gold alloy anodes with a gold content of approx 990-995 ‰ (thousands) every 24 hrs the production of fine gold goes from 6 to 12 kg (and even more) for each of the 2 tanks that are seated in the plant.

Technical Features:

  • Main  structure and suction hood made in pps and complete with frontal sliding transparent panel.
  • 2 electrolytic tanks made of pps with 20 mm thickness.
  • Electrolytic tank dimension:500x300x400h mm each.
  • Approx volume= 40/45 liters each tank
  • Suction system under the hood.
  • Grazing suction system over the tanks
  • Suction pipeline placed behind the hood.
  • This pipeline is easily dismountable to allow cleaning operations and recovery of the gold chloride deposited inside the pipes during  the electrolytic refining process.
  • Tipping extractable cover over each electrolytic  tank.
  • Removable safety tank placed under electrolysis  tanks.
  • 1 condenser made of pp and complete with  internal pvdf pipe coil placed on the hood side.
  • The condenser must be connected to an external   cooling system.(chiller or water recycling tank
  • That will be quoted separately.  the condenser is also equipped with a  counter-wash system that allows total recovery  of the gold chloride deposited inside the condenser formed during the fumes suction of the  electrolytic refining process.
  • The fumes exit pipe from the condenser is  ø 160 mm complete with butterfly valve.
  • Main switchboard to control all the plant  functions (t° control, recycling pumps etc.)
  • Electrical connection:220 v or 380 v  threephase.
  • Absorbed power: 4 / 5 kw/h approx.
  • Overall dimensions: 1800x750x1800h mm


Each Tank is Equipped With:

  • 1 magnetic propeller pump made of pvdf for  the continuous recycling of electrolytic  solution into the tank.
  • 1 thermo-regulated heater made of Teflon which absorb 1500 watt
  • 1 level control sensor device.
  • 3 rear copper bars (2 positive + 1 negative)  for current rectifier connection and complete  with anodes and cathodes contacts.
  • 5 cathodic bars made of titanium complete  with n°5 special hooks in titanium for holding the cathodes made of rolled thin pure gold.
  • 4 anodic bars made of titanium complete with n°4 special hooks in titanium for holding the gold anodes which are covered with  meraklon cloth bags in order to collect any  eventual metallic impurities.


Chemical Characteristics:

  • With an electrolytic solution containing about  70/80 gr aucl3 in appropriate concentration  each tank can produce about 6/12 kg  fine gold  (999,9) every 24hrs.
  • To increase the production is possible to change  the composition of the electrolytic solution adding more AuCl13


Other Components:

  • RECYCLING TANK FOR WATER USED IN THE CLOSE CIRCUIT COOLING SYSTEM OF ELECTROLYTIC GOLD REFINING PLANT.
    • volume = 1200 lts. approx
    • double reinforcements on the tank
    • recycling pump with immersion impeller 700h mm.
    • main switchboard
    • absorbed power: 0.75 kw
  • STABILIZED CURRENT RECTIFIER TYPE 1000A-10V WITH 2 POSITIVE EXITS AND 2 DIGITAL VOLT-AMPEREMETERS TO CHECK CURRENT IN ELECTROLYSIS CELLS 1 AND 2.
    • max. output: 1000 ampere / 10 volts
    • forced air cooling system
    • overall dimensions: 700x700x1200h mm.
  • 2 POSITIONS HAND-WASH BASIN MADE OF P.P.8 mm WITH FORCED FILTRATION SYSTEM.
    • acid proof discharging pump with filter:0,25 hp.
    • 2 taps, level sensor and decantation tank with cartridge filter
    • overall dimensions: 750x450x1300h mm
    • weight:  approx. 55 kg.
  • THERMOSTATIC STOVE DRYER T5510 FOR DRYING GOLD AND SILVER GRAINS, CRISTALS AND JEWELLERY ITEMS WITH 10 EXTRCTABLE PLANES 50x50cm AND 6 EXTRACTABLE PYREX CONTAINERS
  • FUMES WASHING TOWER Ø 600 mm. FOR WASHING ACID EMISSIONS FROM PRECIOUS METALS CHEMICAL PROCESSES.
    • 1 BASAMENT USED AS RECYCLING TANK.
    • 1 RECYCLING PUMP:0,25 Kw.2750/3350 rpm
    • 1 FUMES WASHING SECTION FILLED OF SPECIAL RINGS.
    • 1 SUCTION FAN: 0,55 Kw – 2700 rpm.
    • 1 MAIN SWITCHBOARD
    • TOTAL ABSORBED POWER: 0.8 Kw. APPROX.
    • OVERALL DIMENSIONS: 700x1500x2800h mm.
