Magnetic resonance imaging (MRI) makes an immeasurable contribution to improving human health. Every day MRI machines help medical professionals save and improve countless lives around the world. It is estimated
Applications for niobium
Niobium consumption is dominated by its use as additive to high strength low alloy steel and stainless steel for oil and gas pipelines, car and truck bodies, architectural requirements, tool
Processing: extraction and refining
Two separate processing schemes are utilized for niobium production. Those companies that mine pyrochlore convert the niobium oxide units into HSLA ferroniobium through the aluminothermic reduction process or by reduction
Production of raw materials
The primary mineral from which niobium is obtained is known as pyrochlore. The world’s largest deposit is located in Araxa, Brazil and is owned by Companhia Brasileira de Metalurgia e
