Metal Concentrators SA (Pty) Ltd is a pioneer in the field of refining and supplying precious metals in South Africa, and has earned a reputation for being an industry trend setter and an ongoing source of inspiration and technical support for jewellery manufacturers throughout the country.
Metal Concentrators – Established 1989
Established in 1989 by Bernard and Hilary Stern, Metal Concentrators offers a wide range of services, including: refining precious metals (scrap and jewellers’ waste material); supplying gold, silver, platinum and palladium; producing carated alloys and master alloys, jewellery findings and rhodium solutions; using computer-assisted design in jewellery casting, finishing and mounting; and manufacturing minted gold, silver and platinum bars.
The company has refineries in Johannesburg and Cape Town and a satellite branch in Durban. It also has a team of representatives who serve South Africa’s jewellery industry on a national scale.
Over the years Metal Concentrators has clocked up several notable achievements, reflecting the company’s commitment to leading the way on the innovation front and delivering excellent customer experiences. In a series of ‘firsts’, Metal Concentrators was the first company in South Africa to receive dual certification (in the form of Chain of Custody and Code of Practice) from the London-based Jewellery Council, which acknowledges high levels of integrity in gold trading. Metal Concentrators was also the first company in South Africa to formulate and produce nickel-free alloys in compliance with the EU Nickel Release Standard.
In addition, Metal Concentrators was one of the first companies to receive permission from the South African Diamond and Jewellery Regulator and the South African Reserve Bank to produce and sell minted gold, silver and platinum bars. These bars meet the SANS 29 standard prescribed by the South African Bureau of Standards (SABS) and carry the SABS quality assurance mark. Metal Concentrators’ operation is also fully compliant with the provisions of the Mining Charter.
Patrons of the South African Jewellery Industry
Metal Concentrators has made a tangible contribution to the growth of the South African jewellery industry by supporting the goals of the Jewellery Manufacturers Association. The Platinum Design Competition, known as ‘PlatAfrica’, is Metal Concentrators’ brainchild. Now in its twelfth year, PlatAfrica is a high-profile initiative that promotes innovation and nurtures new talent in platinum jewellery design and manufacturing. It is sponsored and supported by Anglo Platinum, Johnson Matthey and Platinum Guild International.
A Bright Future Under a New Management Team
In September 2015, the Stern family sold their financial holding in Metal Concentrators to Caxal Enterprises (Pty) Ltd, a privately-owned company.
Caxal Enterprises, as a group, is excited about building on the excellent foundation laid by Bernard and Hilary Stern and taking Metal Concentrators to new heights as a supplier, service provider and guiding force in the refining and jewellery manufacturing industries.
