We perfected this process back in the late 80s for other refiners to refine both gold and platinum group metals safely, while also reducing costs. After working with people who have refined using this method, we've carefully perfected this method through the Simplicity Refining System to make it simple for individuals and companies.

Unfortunately, sulfur oxides are also pretty nasty and smelly air pollutants – which is why there are very few roaster or smelters still operating and doing this type of process in the US. However, this "burning" or roasting of the sulfide ores does work well to convert rebellious ores into a more free milling state, allowing the values to be extracted.
