The Perth Mint, the only LBMA accredited refiner in Australia, currently refines the total annual production of gold in Australia. In addition, gold ore is also sourced from New Zealand, Papua New Guinea, Fiji, Thailand and Malaysia. Gold jewellery scrap is also sourced from a variety of Asian markets. Refinery throughput is expected typically between 300 tonnes and 400 tonnes per annum. Refining capacities are well in excess of this.
The refinery uses three refining processes:
- chlorination electrolytic
- electrolytic gold refining
- electrolytic silver refining
The combination of these three refining processes ensure the most cost effective treatment of gold and silver from mines, industrial scrap, jewellers’ lemels as well as other types of high and low grade material.
For more than a century, The Perth Mint has been providing timely refining advice and service to the Australian gold mining industry and dealers in secondary precious metal scrap.
Built upon the foundation established in 1899 when The Perth Mint opened as a branch the Royal Mint, Tower Hill, London, The Perth Mint has maintained a reputation for the highest standards of reliability, accuracy and integrity.
Attention to maintaining these exacting technical standards has resulted in The Perth Mint - Refining Division's services being recognised and accepted throughout the world. It has provided technical consultancy services to a number of other countries to assist them with the design and development of refining facilities.
The Perth Mint enjoys accreditation as a refiner, weight master and assayer with the London Bullion Market Association (LBMA), the New York Commodity Exchange (COMEX), the Dubai Multi Commodities Centre (DMCC), and the Tokyo Commodity Exchange (TOCOM). This status was achieved only after rigorous scrutiny of standards and procedures and the successful completion of searching practical testing.
The Perth Mint bar mark provides assurance to purchasers anywhere in the world of the stated weight, purity and integrity of the product.
