The mission of AMG Brazil is to produce and sell tantalum concentrate, tin in ingots and feldspar with certified origin to the global market.
Tantalum is characterized as a bluish-gray metal, and it is extremely ductile and malleable to low temperatures. It also has a higher chemical inertia in very aggressive media, due to a thin surface oxide film that covers invisible.
Tantalum concentrate is the feed source used by the processors to produce tantalum capacitor powders and metallurgical products. The concentrate is also used to produce pure tantalum pentoxide (Ta2O5) primarily utilized in the production of optical glass and lithium niobate. The primary feedstock is ore mined at the Volta Grande Mine operations.
AMG also produces niobium oxides. Niobium is used in specialty steel and titanium.
Tin is a malleable metal which is solid at room temperature, not easily oxidized and is resistant to corrosion. Tin ingots are bar metal and high purity blocks, used in the production of castings, forgings and rolled in general.
