Delivery/incoming goods inspection

We use a wide range of inspection techniques to determine the point of origin and processing method required to handle every item delivered to us upon its arrival. The item is then sealed back up and confirmation of receipt is provided.

The processing method used (smelting, grinding or incineration) varies based on the item’s constituent materials. Once the incoming goods inspection is complete, we are able to carry out our calculations and confirm the payment method. Each job load is analysed separately and recorded in SAP under an individual identification number, which guarantees that items remain traceable at all times.  This is where the accuracy and efficiency of our approach sets us apart, as it means that we can offer our customers a streamlined, swift service while keeping them up to speed at every stage of the process.

Homogenisation – analysis – reimbursement

The techniques used in the homogenisation stage depend on the materials being processed. In smelting, the molten material is poured into casts and homogenised as ingots.  Certified metallurgical assayers at our accredited analytical laboratory then determine the purity of the metal by analysing samples taken from each ingot.

It is at this point that the customer is either paid or has their account credited. What makes Cendres+Métaux Luxury+Industry stand out is the sheer speed of this process, which minimises any risk related to the exchange price of precious metals.

Having been analysed, the ingots are then moved on for refining. The metals are selectively broken down and we extract precious metals such as gold and platinum in an extremely pure form.

“Waste” or “low-grade” materials are incinerated, then the ash is ground, resulting in homogenisation. This process enables us to remove any organic matter. The remaining material is then tested in our accredited analytical laboratory and the customer is paid.

Here's how it works

Due to legal regulations we are obliged to verify the identity of our customers and the legal origin of the precious metals which are handed over to us for processing.

No assets are accepted which come from criminal activities, originate from criminal or terrorist organisations, or which are used to finance the same.

Conditions for the acceptance of waste precious metals

  • Originates from a business that holds the necessary approvals
  • The relevant obligations according to the Precious Metals Control Act (PMCA) and the Anti-Money Laundering Act (AMLA) have been fulfilled
  • Foreign goods can only be accepted if accompanied by proof of correct importation into Switzerland (import declaration)
  • The approval to exercise intermediation in the finance sector according to Art. 14 AMLA must exist
