Abstract: In this study, it was possible to optimize the hydrometallurgical extraction conditions of tin from cassiterite ore in Kalima (DR Congo) by an alkaline smelting process with an equimassic mixture of NaOH and KOH. This ore was characterized by a 68.58% tin content in a siliceous gangue incorporating other elementsWeb
