The price of the tantalite is very much dependent on the demand as well. The price of tantalite ore rose from about $75 per kilo in 2010 to more than $270 per kilo on 2011 and 2012. But the price has dropped since then. However, some experts point to expected growth in the electronics, aerospace, and power industry to boost the price …

Jere et al. (1961) studied the thermodynamic basis of chlorination of oxides present in columbite-tantalite ore. Standard free energy and standard enthalpy change as a function of temperature was calculated. The results confirmed that Nb 2 O 5 had great tendency for chlorination at about 250 °C.

The increased demand of metals such as tantalum (Ta) and niobium (Nb) reflect the on-going development in modern science, engineering and technology. The extraction of these two metals from columbite-tantalite ore is based on generic extractive metallurgy. However, the upstream purification of ore and downstream extraction of Ta …
