Tantalum Mining | Processing Equipment | Flow Chart | Cases
The tantalum concentrate is transported to the processor for chemical processing. The concentrate is then treated with a mixture of hydrofluoric and sulphuric acids at high temperatures. This causes the tantalum and niobium to dissolve as fluorides. Numerous impurities are also dissolved. Other ores, such as silicon, iron, manganese, titanium ...Web
