CopperstoneResources AB (publ) and GreenIron H2 AB started a joint development project, based on GreenIron's fossil-free reduction process and Copperstone's future by-product flows from planned copper and magnetite mining. The project intends to optimize material handling both before and after GreenIron's process. Copperstone will contribute with material handling and analysis and GreenIron will contribute witha fossil-free process to reduce metal oxides to metals.

The project, which is supported by Vinnova with SEK 17 million, will increase understanding of the process itself as well as the various process steps that exist before and after the reduction process itself. This also includes that GreenIron will build a full-scale demonstration plant. GreenIron has a unique process for the reduction of various metals which, in contrast to today's conventional processes, is completely fossil-free and operates at a significantly lower temperature, is silent, energy efficient and the only residual product is water.
