  • Gold is recovered from industrial, dental, porcelain or jewellary scrap. For refining, gold bearing alloys are processed on different methods, depending on their carat content.
  • Two methods are commonly employed for purification: the Miller process and the Wohlwill process.
  • Alternatively, it can be a complex mix of burning, drying, grinding, screening, blending and sampling for low-grade scrap and floor sweepings. Whatever the material, proper evaluation is key to arriving at a settlement that is fair to both customer and refiner.
  • The proportion of gold in jewellary is measured on the carat (or karat) scale. The word carat comes from the carob seed, which was originally used to balance scales in Oriental bazaars. Pure gold is designated 24 carat, which compares with the "fineness" by which bar gold is defined.
  • The most widely used alloys for jewellary in Europe are 18 and 14 carat, although 9 carat is popular in the UK. Portugal has a unique designation of 19.2 carats. In the United States 14 carat predominates, with some 10 carat. In the Middle East, India and South East Asia, jewellary is traditionally 22 carat (sometimes even 23 carat). In China, Hong Kong and some other parts of Asia, "chuk kam" or pure gold jewellary of 990 fineness (almost 24 carat) is popular.
  • India being the largest consumer of gold jewellary and with a very low production of gold, it largely depends on imported fine gold.
  • Indian jewellary has huge demand in world with estimated exports worth US $ 3,813 million in 2004 - 05.
  • South Africa is the world's largest producer of gold, followed by USA and Australia. Together, these countries account for 45 % of the world's total gold production.
  • India is the largest consumer of gold, followed by the USA. The global gold production rate is expected to increase at 4%.
  • Annual demand for gold falls into three main categories, the largest of which is the jewellary market, which was worth $40 billion in 2005.
  • Valcambi refines mine and scrap precious metals, manufactures kilo, 10 tola, 100g bars and investment bars for global markets, semi finished products for the luxury Swiss watch industry and coins. Finorafa is a major supplier, distributor and financier of precious metals to all major markets, currently provide over $500m of precious metals financing to investment rated banks.
  • Desktop Gold Refining equipment & initial consumables cost about USD 1500
  • The project can be a good source of income considering the simplicity of operation, low investment , availability of plenty of Scrap and more interestingly Gold prices scaling new hights during & future days
