Example oxidation of manganese dioxide Consequential LCA
Manganese dioxide is an inorganic compound with the formula MnO 2 which is a precursor for KMnO 4 (Potassium permanganate) and K 2 CO 3 (Potassium carbonate)(Open Chemistry Database 2015a and 2015b). Potassium permanganate is a strong oxidizing agent and is used as an oxidizing agent in many chemical reactions.

Manganese dioxide Wikipedia
In a classical laboratory demonstration, heating a mixture of potassium chlorate and manganese dioxide produces oxygen gas. Manganese dioxide also catalyses the decomposition of hydrogen peroxide to oxygen and water: 2 H 2 O 2 → 2 H 2 O + O 2. Manganese dioxide decomposes above about 530 °C to manganese(III) oxide and oxygen.

ATSDR, 2000). Manganese dioxide and other manganese compounds are used in products such as batteries, glass and fireworks. Potassium permanganate is used as an oxidant for cleaning, bleaching and disinfection purposes (ATSDR, 2000; HSDB, 2001). Manganese greensands are used in some locations for potable water treatment (ATSDR, 2000).
