Your Trusted Gold Refiner
Refining Systems Used to Make Gold Bars - Electrolyte Process
Electrolyte process is for the end-use consumers who need gold in purer form. The .995 pure gold is melted and cast into an electrode called an anodes. The anode is placed in an electrolyte solution with cathodes.
Refining Systems Used to Make Gold Bars - Chemical Treatment
Refining gold using chemicals is another common method. Gold is treated with sulphuric, hydrochloric or nitric acids.
Refining Systems Used to Make Gold Bars - Smelting Gold Ore
Refining can be done in another way by using silica, soda ash and borax. These chemicals are mixed with gold ore to make dried precipitate which is heated in a blast furnace.
Refining Systems Used to Make Gold Bars - Cupellation
As the ore melts, the slag that floats on the top of the mixture contains impurities which have been drawn out of the gold ore.
Urban Mining - reduce the pressure on demand for primary raw materials
It is clear that as the demand for raw materials increases, greater efforts will have to be made on recycling. Flow of precious metals recycling is crucial.
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.
Urban Mining - reduce energy consumption, greenhouse gas emissions and other negative environmental impact from extraction and processing
Higher recycling rates.
Urban Mining - Refine AU's areas of expertise within raw materials recycling cover the following metal groups:
• Rare metals (RE, In, Ta, Li)
• Light metals (Al, Mg, Ti)
• Precious metals (PGM, Ag, Au)
• Base metals (Cu, Zn, Pb)
Metallurgical Assay - The most elaborately accurate, but totally destructive, precious metal assay is fire assay
It may also be called by the critical cupellation step that separates precious metal from lead.
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.
