Copper Slag is by-product or waste stream from the production of copper. The smelting process produces a glass like substance that will settle on the top of the melting copper and is basically the non-copper impurities being separated. The slag is then skimmed off the melted copper and delivered to a “slag heap” or slag dump where it is left to cool. Once cooled the slag is broken up with heavy machinery, cleaned up and used for multiple industrial purposes which we will discuss. Years ago, the copper slag was considered a useless waste stream and it was covered up or moved and buried. In the late 1990’s there was a movement to reuse industrial waste streams when possible. Slags have always been used in some capacity for simple construction purposes such as roads and back fill. Only in recent years have the uses for cu slag expanded and this is due to research and the need to keep materials out of landfills or possibly causing environmental issues with by-products.

Copper slag has many industrial uses that range from basic construction materials to fine high quality sand blasting media. Quality copper slag has been compared to coal slag for its versatility in sand blasting. Raw copper slag must be processed from its raw form to meet the high quality and safety standards needed for the sand blasting media market. This marketplace was valued at 9 billion USD in 2020 and is expected to grow at a pace over 5% in the years to come. This is an excellent opportunity for companies looking to expand into this marketplace. Saucon Minerals is offering a trusted and proven supply of high-quality raw copper slag for this market.
