GOLD REFINING PLANT - 2 KG/BATCH – BY AQUA REGIA PROCESS

It can be used for refining both metal granules and powders.

Refining plant for gold alloys up to 2kg capacity of input material per batch.

It represents a versatile model of refining unit:

• refining alloy by aqua regia with Au min. 65% and Ag max 15% content;
• refining low karat alloy by inquartation.
• 
  

Processing capacity (input material as powders): depending of the volume/specific weight

The Gold Refining Unit is made of the following components:

• Polypropylene cabinet with integrated suction system for vapors
• Loading tank for acids with tap
• Reactor 1 for alloy leaching with heating system for quick and efficient digesting reaction
• Reactor 2 for AgCl filtration and Au precipitation
• Reactor 3 for Au filtration/effluent discharge
• N. 02 Filter Units: one for silver as AgCl and one for pure Gold (AU ≥ 999.5)
• N. 01 Automate dosage system for precipitation process
• Devices included:
• heating system: Oil bath heater for Reactor 1
• vacuum pump for liquids transferring
• valves panel for flow regulation
• pneumatic control board
• mechanical stirrer pneumatically activated
• electrical control board
• AODD discharge pump for effluents
