As I am about to submit this dissertation for the award of Ph.D. degree, I must acknowledge that this has been the most venturesome odyssey of whole of my personal, professional and academic life till date. In the process many hurdles and challenges of monstrous proportion came crashing upon me which nearly derailed my journey.

of slag splashing in steelmaking furnaces has extended the life of refractories wherein the viscous slag is splashed on the sidewalls of the furnace at the end of the blow forming a protective adhesive layer. However, due to process differences, similar techniques cannot be used in the non-ferrous industry.

The advancement in computational thermodynamics can help researchers to test their hypotheses regarding complex steelmaking operations in a more quantified manner. The main aim of the current work was to use develop a kinetic model that can predict changes in steel, slag and inclusions during ladle refining and use this model as a tool to develop better understanding of the steelmaking process

The beneficiation was successfully performed using shaking table concentrator and carpco magnetic separator. The enrichment ratio reached up to 160-times for both Ta 2 O 5 and Nb 2 O 5. Aliquat 336 ionic liquid was used for separating Ta 2 O 5 with purity of 90%. Amberlite anion exchanger was used for separating Nb 2 O 5 with purity of 87%.
