Companhia Brasileira de Metalurgia e Mineração (Portuguese for Brazilian Metallurgy and Mining Company), or CBMM for short, is a Brazilian company that specializes in the mining and processing of niobium, extracted from its pyrochlore mine near the city of Araxá, in the Brazilian state of Minas Gerais, where the company is also headquartered.
CBMM is by far the world's largest producer of niobium metal and its basic alloys, providing over 80% of the world's supply. Like the other producers of this metal, the company does not sell raw niobium ore, only ferroniobium, other niobium alloys and oxides, and the pure metal, all produced in its facilities next to the open-pit mine. As of 2016, CBMM produces 90,000 tonnes of ferroniobium equivalent per year, which is slated to be increased to 150,000 tonnes/year. The Araxá ore deposit is large enough to supply the market demand for at least 200 years at current consumption rates. CBMM was the world's first mining and metallurgy company to be ISO 14001-certified.
