REVIEW ON KEY PARAMETERS DURING CARBOTHERMIC REDUCTION OF TIN FROM CASSITERITE

Abstract

Due to the sudden sharp increase in tin demand, the production of tin through carbothermic reduction process requires refreshment by assembling important required data and disseminate to the potential producers. The current paper presents a review on different parameters that have been tested on different tin ores. Basicity, although simply defined as ratio between the basic oxides and acidic oxides, more information unfolds depending on whether the basic oxides or acidic oxides can be interchanged or replaced by another. The effects of interchanging a basic oxide by another on the kinetics and the slag composition and behaviors are discussed in the current paper. Since different ores have different compositions the adjustment of basicity may require different basic or acidic oxides. Different effects of such parameters on the carbothermic reduction of tin are here gathered and discussed.
