Electrolytic manganese dioxide (EMD) is a material that is important in battery production and water treatment. Manganese for EMD comes from a manganese oxide compound called pyrolusite in manganese ore. Pyrolusite cannot be dissolved in any common solvents (think liquids) but other manganese oxides can be. So, to extract manganese from its ore, the ore is heated in the presence of what is called a reducing agent to chemically transform the pyrolusite into a manganese oxide that can then be dissolved in sulfuric acid. This process involves the combustion of fossil fuels and the use of carbon containing reducing agents which gives it a large carbon footprint. I study an adaptation to that process in which a reducing agent, hydrogen peroxide, is added directly to the sulfuric acid to chemically transform the pyrolusite as it is being dissolved. This is a less energy-intensive process which can help decarbonize EMD production. This adapted process will make EMD production more sustainable and contribute to our clean energy future.
