Gold Refining Plant Manufacturer and Supplier
Karat24 Project is a leading manufacturer and exporter of gold refining plants in India, offering a solution for businesses worldwide to achieve high-purity gold recovery.
We understand the diverse needs of our clients and provide a range of customizable gold refining systems to suit your specific requirements.
This article introduces our exceptional gold refining plant, capable of processing raw materials ranging from 300 grams to 10 kilograms.
In a single production cycle lasting 5 to 8 hours, you can achieve 99.99% pure gold (Au) ingots, ready for further use in your business.
The Power of Aqua Regia
Our system utilizes the well-established Aqua Regia process. This method is ideal for gold-bearing materials with a minimum gold content of 65% and a maximum silver content of 10%.
Aqua Regia is a potent mixture of hydrochloric acid (HCl) and nitric acid (HNO3) that dissolves the raw metal alloy. Silver precipitates as silver chloride, which is then removed through filtration.
The remaining solution containing dissolved gold is treated with a reducing agent, typically sodium metabisulfite, to precipitate pure gold. This gold precipitate is then filtered, washed, dried, and can be melted into a final gold ingot.
Inquartation: An Alternative for High-Silver Alloys
While Aqua Regia is highly effective, it has limitations with materials containing high silver content (above 10%). In such cases, we recommend the inquartation procedure.
Here, the gold is diluted to around 25% by melting it with copper or silver. This “quartered” gold alloy can then be treated with nitric acid, which dissolves the silver and base metals, leaving behind pure gold.
Four Simple Steps to Pure Gold
Our gold refining plant simplifies the gold recovery process into four key stages:
Dissolution: Acids react with the gold, silver, copper, and other constituents of the alloy. This results in a gold chloride solution, silver chloride precipitate, and copper nitrate solution.
Filtration: The silver chloride precipitate and any insoluble matter are separated from the solution containing dissolved gold and copper.
Reduction: A gold reagent is added to the solution, reducing the gold chloride to pure gold oxide precipitate.
Washing: The gold oxide is separated from the remaining copper-containing solution, washed thoroughly, and dried. You can then melt the gold powder for further use.
Gold Refinery Plant: Comprehensive Features
Our gold refining plant incorporates a variety of components to ensure efficient and safe operation:
Dissolution Reactor: This cylindrical borosilicate glass reactor has a 50-liter capacity and features a discharge valve for easy material handling. A PTFE stirring mechanism with a 0.5 HP gear motor ensures proper mixing. The reactor also includes an electrical heater with temperature control and a glass condenser for fume recovery.
Precipitation Reactor: This 100-liter borosilicate glass reactor features a discharge valve and a PTFE stirring system for optimal processing. A dedicated gold reagent charging system is included for efficient gold precipitation.
Gold Filtration Unit: This polypropylene (PP) unit removes used silver and other metals, allowing only the gold solution to proceed to the precipitation stage. An air-operated filter pump ensures efficient filtration. The unit is movable for ease of use and features a safety cover for operator protection.
Scrubber Unit: This three-stage unit effectively neutralizes acid fumes generated during the process. The pre-washing stage handles acid fumes, while the final stage utilizes a carbon air filter to eliminate any remaining contaminants from the exhaust.
Electrical Control Panel: The control panel features separate MCBs for each motor, ensuring safety and ease of operation. It includes controls for stirring speed, temperature, and emergency shutdown. Additionally, the panel is equipped with country-specific power supply compatibility.
Single Batch Processing and Specifications
Our gold refining plant is designed for single-batch processing, handling alloy batches from 1 kilogram to 6 kilograms. Depending on various factors, a complete working cycle can take approximately 24 hours, allowing for three batches per day.
The achievable purity of the final gold product ranges from 999.5 to 999.8-9/1000, and the plant operates on a three-phase (3Ph) electrical power supply.
