0.25 gram Tavex Gold Bar

Minted  bars  refer  to  the  manufacturing  process  that  is  applied  to  create  them.  The  process begins  by  heating  gold  material  in  a furnace  until it  turns  to  a  molten  slurry.  During  the heating process, all unwanted impurities in the slurry are removed until only molten gold of high purity is left, most often at around 99.99%. The molten gold is then poured into moulds, usually in the shape of large bars, where it cools and solidifies. The solid gold is then inserted into  a  mill  that  rolls  the  gold  into  panels  with  a uniform  dimension.  Afterwards, the  gold panels are inserted into a blanking press that punches blanks out of the gold panels. The next step  involves  the  weighing  of  each gold  blank  to  ensure  that  it  is  neither  underweight  nor overweight and those that pass this test are then polished for them to obtain a shiny surface. The  last stage  involves the  minting  process where the  gold  blank  is  inserted into a  minting press  that  presses  its  die with  huge  force  to transfer  the  design  from  the  die  onto  the  gold blank. The result is a  minted bar. The newly  minted gold bar is then inspected before being sealed in a transparent tamper-proof protective package.

Nadir Metal Rafineri San ve Tic. A.Ş started out as Nadir Tütüncü's small workshop to recycle jeweler dross in 1967. Beginning from 1975, it started precious metal refining for the market and the workshop increased in size limited to this field. 

In 1999, a partnership agreement with the German company Degussa Allgemeine was signed in exchange for technology “know-how” and thereby Nadir Allgemeine Ind.Trade.Co.Ltd. was established. In 2001, Nadir Family became the sole shareholder of the company which continued its operations under the name of Nadir Metal Rafineri San. ve Tic. Ltd.  After the accretion agreement in 2001, all the infrastructural investments were completed within a year. In 2006, Nadir became a joint stock company with its new title: Nadir Metal Rafineri San ve Tic. A.Ş.

The company was accredited by Istanbul Gold Exchange (Borsa Istanbul) in January 2008, by Dubai Stock Exchange (DMCC) in October 2009 and by London Good Delivery Association (LBMA) in December 2011.

Today, along with refining, waste recycling, dross and laboratory services, Nadir Metal produces and trades precious metals (gold, silver, platinum, palladium, and rhodium). In addition to these, “Nadir Metal” and “Nadir Gold” branded small bars of gold, silver and platinum products and exclusive collections are produced.
