文摘
- •
Sodium stannate preparation from stannic oxide by soda roasting–leaching was proposed.
- •
Effect of roasting and leaching parameters on the Sn leaching efficiency was tested.
- •
Na2SnO3 was easily formed when SnO2 and Na2CO3 were roasted in a CO/CO2 atmosphere.
- •
Na2SnO3 · 3H2O with 95.8% purity was obtained from the cassiterite concentrate.
- •
Final Na2SnO3 · 3H2O meets the demand of industrial first-grade product.
