FEATURES UGLETERMICHESKOGO RECOVERY CASSITE-RITE IN IONIC MELT
Studied the process of ugletermicheskogo recovery kassiteritovogo concentrate in ionic molten salt systems Na2CO3 NaNO3 (1:0,3). The composition of the furnace charge, defined temperature interval of the recovery process (600-900 OC). Studied that interaction of cassiterite with the melt is formed intermediate connection Na2SnO3 that recovers mainly gas FROM the liquid phase melt with high speed (1.5 hours), providing completeness of extraction at the level of 97% tin from kassiteritovogo concentrate in the draft alloy
