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
