Niobium is a shiny, white, ductile metal. In air an oxide layer forms whose color depends on its thickness. Shades of blue, green and yellow are typical. Niobium resists corrosion due to the oxide film. The metal starts to oxidize rapidly in air at 200 o C.
Brazil: Niobium, National Mineral Wealth at Knock Off Prices?
· Global annual consumption of ferro niobium is over 200 million pounds per year and growing at 57% per year. Two hundred million pounds correspond to approximately 90,718 metric tons. While the average selling price has decreased in the last five years, exploitation and consumption of the metal has increased worldwide.
· Niobium (symbol: Nb; atomic number: 41) is a metallic element with soft, gray and ductile properties. In nature, it is often found along with pyrochlore mineral while its processed form is used in the manufacture of highgrade structural steel and superalloys. The name comes from Niobe, a figure in Greek mythology, who was Tantalus' daughter.

· World niobium production is 68,000 tonnes, 88% of which is from a mining complex in Brazil. Another 10% is from at a mine in Canada, and the remaining 2% comes from Africa and Australia. The estimated price for 2018 US consumption was /lb. The niobium market has been very stable for years, and the increase in US consumption was absorbed ...
To calculate the value of a niobium mineral, the main principle is that only the quantity of Nb 2 O 5 +Ta 2 O 5 contained is paid for, not the whole bulk of material. Basically, the weight of material is multiplied by the percentage grade 50% Nb 2 O 5 +Ta 2 O 5, then multiplied by the pricing rate of X/lb Nb 2 O 5.
