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 …
fusion and in the optimization of the water leaching parameters of niobium and tantalum contained in the Manono ore in the Republic Democratic of Congo. The ore studied is a columbite containing approximately 53% in Nb 2 O 5, 30% in Ta 2 O 5, 7% in SiO 2, 5% in SnO 2 and 3% in Fe 2 O 3. Indeed, the use of ore/ NH 4 HF 2 /KOH
hydrometallurgical properties of tantalite ore. Tantalum ore leaching parameters like temperature, time, and particle size have all been investigated before [14,15]. The quantity of U and Th metal ions leached from tantalite ore revealed a significant amount. Further-

Because the tantalite-columbite deposits at Kenticha have higher tantalum concentrations than niobium (Ta:Nb is up to 3:1), we will refer to this ore as tantalite. The tantalite production is relatively small, but the reserves are large and estimated at 20,000 tonne of T 2 O 5 and Nb 2 O 5.
Despite this fact, Nb and Ta worldwide exploitation comes from ore sources mostly found in Brazil (above 90% of Nb production), Canada, and African countries, …
