REFINING OF TANTALUM AND TANTALUM SCRAP WITH CARBON
摘要
<p>Tantalum scrap of high oxygen content (10) is recovered and processed to metallurgical grade tantalum by fine particulation. Blending with carbon or other appropriate solid reducing agent (14), melting in a plasma furnace (20) at about tantalum melt temperature while suppressing partial pressure of tantalum oxide gas to minimize tantalum loss of the process.</p>
