CBMM's headquarters, mine, manufacturing facilities and technology center are located in Araxá, Minas Gerais, Brazil. Even though the Company mines the largest known proven reserves of pyrochlore (niobium-bearing mineral) in the world, it continuously invests in the optimization of extraction and ore processing procedures in line with its management approach to conscientiously use natural resources and raw materials.
CBMM sells only niobium finished products. No amount of niobium ore leaves Araxá without being transformed into higher value-added, finished niobium products.
The Company developed and continuously improves the technological processes involved in each of the 15 steps that comprise niobium product manufacturing.
Decades of investment in the technology of niobium products and processes have resulted in the Company's cutting-edge facilities to process pyrochlore and transform it into some of the most sophisticated solutions to the challenges of the modern age.
The evolution of CBMM's processes and production capacity.
