Established in 2003, Sinar has been purchasing and refining scrap gold from private individuals, pawn shops, and goldsmithing workshops to be crafted into jewellery for nearly 2 decades. It is situated upstream in the Mega Group’s gold supply chain, supplying Le Grand with the raw material required to produce the gold jewellery sold in bulk by Mega.
” Satisfying Demand for Gold While Minimising the Environmental Impact of Resource Extraction “
The Rationale Behind Repurposing ‘Second-Hand’ Gold
Gold mining, and mining in general, wreaks huge environmental destruction. To found a new mine, large swathes of vegetation must be cleared, thus destroying the habitat of countless local flora and fauna. Once gold ore is brought to the surface, pure, elemental gold must then be extracted using a toxic mixture of mercury and strong acids, which is all too often indiscriminately discharged into surrounding waterways. Purchasing and recycling scrap gold helps reduce demand for new mines (and the associated environmental destruction) by offering consumers an alternative supply of gold.
Recycled gold is in no way inferior to gold freshly extracted from mines; on the contrary, it is just as pure and durable as ‘fresh’ gold after undergoing refining. As a bonus, gold scrap is often cheaper than ‘fresh’ gold by weight, allowing the Mega Group (via Sinar) to both lower inventory costs and pass on these savings to customers in the form of better prices. Discerning customers will then flock to the Mega Group over our competitors for an unbeatable combination of attractive pricing and internationally- recognised quality.
The Gold Recovery Process
1 Recovery Solution
Scrap Gold
Scrap gold is sorted based on its purity, e.g. 24K / 22K / 18K / 14K / 9K etc.
The different categories of scrap are immersed in recovery solutions containing nitric acid and hydrochloric acid to dissolve the gold and other substances present in the scrap. The exact formulation of the solution varies depending on the purity of the scrap.
2 Filtration & Precipitation
Gold Solution
The solution is filtered to remove all impurities (basically any substances other than gold, e.g. silver). The remaining gold precipitate is cooled and dried to obtain gold powder.
3 Cooling
Gold Powder
The gold powder can now be melted to form bars and ingots for further processing.
