By: Keagan Lamb

Refineries are able to process and purify precious raw or scrap metals. This article takes a look at some of the most common services that are offered by precious metal refineries, and how you can go about finding and selecting the best precious metal refinery for your needs.

Refining Precious Metals

Precious metal companies will often have one or more refineries. They will be able to process a number of previous metals, including gold, silver and platinum group metals. The methods used to refine precious metals will depend entirely on the type of company you choose to use. Common methods include using electrolysis, wet chlorination (aqua regia) and wet chemical parting. After the refining of the precious metals takes place, clients will be able to receive the final product in either bars, alloys, sponge or as a salt (crystal and solution). A specialist will be able to inform you of the best methods of refining for your needs.

Scrap Gold

Refineries will be able to process and refine scrap gold to a high level of purity, typically to a minimum of 999.9 (four-nines) and up to 999.99 (five-nines). Scrap gold is refined to such a high standard that it can be used in electronics, or by the jewellery making industries. Some companies will also purchase scrap gold from the market and other suppliers.


A professional precious metal refinery will be able to organize all aspects regarding the transportation of the precious metals. Many companies will provide a door to door service, alternatively pick up and drop off collections can also be arranged according to your requirements. They will also be able to arrange secure international freight shipping of your products if it is needed. All transportation of the precious metals will be secure and fully insured by the refinery.


A refinery will have a professional team of trained assayers who will work in accordance to local laws and regulations. They will ensure that all of the processes in the refinery are completely independent of outside influences. They will also be able to determine the quality of the products. A great refinery will send regular samples to a laboratory, where the samples will be checked for precise determination.

How to Find a Precious Metal Refinery

All major precious metal refineries will have a website, where you will be able to view information on the services that they offer, as well as their contact details. You can find these companies by searching for them online. Always pick a reputable and well trusted company to ensure that you will be receiving a high quality service. You can do this by asking several questions when you first make contact with the refinery. This can include things like:
