Precious metals play an essential role in building more sustainable societies. They are used, for example, as catalysts in controlling automotive exhaust emissions. Precious metals can be recycled an infinite number of times. Metso Outotec’s pyro- and hydrometallurgical technologies are well suited for the processing of secondary raw materials, including valuable metals like copper and platinum.
The Planet Positive multi-purpose Ausmelt™ and Kaldo™ processes can be used for integrated primary smelting and standalone smelting, complemented with efficient gas cleaning systems. Further refining can be accomplished with Metso Outotec’s state-of-the-art electrorefining and electrowinning processing technologies. The Metso Outotec DC furnace is based on proprietary technology featuring advanced environmental performance and efficient slag and alloy separation providing high metal recoveries.
