Aldango LTD-Certified Lab Engineers use the Fire Assay Method, also known as the Cupellation Method, to determine the concentration of gold and silver. Small sample of material has its precious metals chemically separated from the impurities and base metals contained in these materials.
Aldango LTD specialises in melting of gold and silver through a High Performance Electric Induction Furnace. This environmentally friendly technique enables us to convert large lots of gold and silver into grains or bars of several sizes and purity levels.
