OUR COMPANY
Refine Au Sdn Bhd specializes in recycling and refining precious metals, particularly gold from used jewellery and e-waste. Their eco-friendly processes not only reduce hazardous waste but also allow gold to be reused in jewellery. We produce gold bars, ingots, and bullion with up to 999.9 purity, ensuring top-quality standards through advanced testing technologies like ICP-OES.
Committed to sustainability, Refine Au adheres to strict environmental regulations and continuously invests in cutting-edge refining technologies. Their SIRIM QAS Product Certification License highlights their dedication to producing high-quality products that meet international standards, solidifying their reputation as a trusted leader in the industry.
Your Trusted Gold Refiner
Refining System Used to Make Gold Bars – Aqua Regia Process
The aqua regia gold refining process uses a mix of nitric acid and hydrochloric acid to dissolve gold. After the gold is dissolved, a chemical is added to separate the gold from impurities. This process produces very pure gold, often up to 99.99% purity. It's a common method used in gold refining.
SIRIM Certified and Trusted Leader in Gold Refining
Refine Au has earned the prestigious SIRIM QAS Product Certification, a mark of quality that ensures its gold refining processes meet national and international standards. This certification, along with our advanced technologies and eco-friendly practices, makes Refine Au a trusted leader in the precious metals industry.
Smelting Gold Bars
Smelting gold bars involves heating gold above 1,064°C to remove impurities, aided by flux like borax or silica. The molten gold is then poured into moulds to solidify into bars of specific weights. For higher purity, further refining methods like electrolysis or acid treatments may be used.
999.9 Gold Purity with Agilent 5110 ICP-OES Technology
Refine Au employs the latest Agilent 5110 ICP-OES instrument, a cutting-edge technology in the gold industry, to analyse precious metals with unparalleled precision. This allows us to detect gold purity up to 999.9, ensuring the highest standard of quality in our products.
Gold Assay
We provide gold fire assay services, delivering precise and reliable measurement of gold content for accurate purity verification.
Urban Mining - help to reuse valuable materials which would otherwise be wasted
Recycling of metals in order to successfully recover raw materials from urban mines, a systematic recycling approach with effective recycling schemes is necessary.
Fire Assay / Cupellation - Cupels for assays and refining noble metals
Cupellation was one of the most common processes for refining precious metals. By then, fire assays were used for assaying minerals. Cupellation is still in use today.
Elemental Purities by ICP - Analysing Precious Metal Content
Accurate precious metal analysis is routinely carried out to determine the precious metal content in a wide variety of different materials.
