Refining Process

Refining of Precious Metals Recyling

  • Precious metal scrap is weighed
  • The scrap is smelted in an induction furnace, a gas blast furnace, or by blowtorch
  • Materials such as borax and soda ash are mixed in to absorb impurities
  • A sample of the mixture is tested to determine the amount of precious metal

As the major precious metal refiner in the world we can offer the best refining package suited to your needs. With our state of the art process, wealth of knowledge and technical know-how, we will help you maximise the value of your scrap material. No requirements are too small or too large; we refine anything from gauzes and metal recovered during plant cleaning, to ACT™ coatings and precious metal fabrications.

Unlike most refiners, we return on all of the precious metals in your scrap. We have an honest, transparent and professional approach, with all refining conducted on our site. We are clear about the returns you are receiving, how long the metal takes to settle and the processing charges.

Keeping scrap segregated and uncontaminated allows us to offer faster and cheaper refining, providing better returns. If the metal is kept absolutely clean it does not have to be de-alloyed, so can be processed back into useful material.

If you would like reassurance of our care and diligence with your scrap, we can arrange an independent inspection for all or part of the refining process, or you are welcome to view the process yourself.

We are able to offer all customers a metal pool account to hold your previous metal and deal with your refined materials. The settled metal can then be sold for full credit, returned physically, or held on account for future orders without being affected from metal price fluctuations. We can also advance metal that is in the refining process, offsetting the amount of new metal you need to purchase for another order.

Silver Refining

Silver refineries provide an economical and environmentally friendly precious metal recovery service. We are scrap silver buyers that specialize in separating silver from other precious metals and waste materials. Precious metal scrap such as silver leaf, silver metal foil and antique silver is weighed and then smelted. As the silver scrap liquefies in the furnace, borax and soda ash are mixed in to separate the pure silver from other precious and non-precious metals.

A sample is removed for assaying, which is the process of measuring the silver content. Assaying is critical for assuring customers who sell us their materials for silver refining that we fairly compensate our customers. For maximum accuracy, we use the Fire Assay and Inductively Coupled Plasma (ICP) Spectrometry methods. The X-ray fluorescence (XRF) method may also be used as needed.

Recycling Electrical Contacts Scrap

Electrical contacts are used in all electronic devices engineered and manufactured today - thermostats, stoves, washing machines, heaters, circuit breakers just to name a few. They can be found in electrical switches, relays and breakers. Electrical contacts are installed in moving and permanent components in many technological devices, such as automotive and aerospace components, high- and low-power contact joins, sliding and breaking contacts, and electro-mechanical systems. Braunović defines electrical contact as a the interface between the current-carrying members of electrical or electronic devices that assure connectivity of electric circuit.

Both electrical and mechanical wear contribute to the loss of contact material. In order to increase the corrosion resistance and lifetime of electrical contacts, manufacturers use precious and semi-precious metal alloys. Silver, fine grained silver, mixes of silver with nickel, iron graphite, cadmium oxide, and tin oxide are used in the electrical contact manufacturing.
