Abstract: Tin slag a waste product of tin smelting contains many important metals such as niobium, tantalum, manganese, iron, aluminum, titanium, etc. Niobium metal which is one of the important metals found in tin slag has successfully been extracted using leaching and electrothermal method. The tin slag was crushed and ground to very fine particle sizes of nanometer level using laboratory ball mill, piston and mortar. The particles were sieved and 150nm and 180nm particle sizes range were used for this experiment. The samples were subjected to two leaching processes using hydrochloric acid and sodium hydroxide. The residues from the leaching processes were subjected to carbonchlorination at 300oC to produce Niobium oxide. The purity of Niobium metal extracted was calculated to up to 95% which means that tin slag from Nigerian Tin Smelting Company is a good source of high quality Niobium metal.
