The company started operations in the Nonoalco open pit mine in 1964, which is in the same district as Molango, which allows obtaining a manganese mineral that is very scarce in the world: Natural Manganese Dioxide (MnO2). With this finding, the company dedicated all resources to process this product, by using advanced technology.
It successfully achieved the introduction of Natural Battery Grade MnO2 in the market as an essential raw material for manufacturing dry batteries.

Throughout the years, the company has become one of the main producers of this material in the world. It has solid commercial relationships in Mexico, the United States, Asia, South America and Europe. Later on, during the 90’s, Autlán ventured in the manufacturing of Natural Ceramic Grade MnO2, thus achieving its acceptance as a pigment in the ceramic industry.

Likewise, during the same decade, the company began processing a new product: Manganese Oxide (MnO), in order to meet the needs of companies producing fertilizers and micronutrients for animals, this at an international level. Autlán has proven reservoirs in Nonoalco, which guarantee the continuous supply of its products to all its customers.
