Investigation of Dissolution Kinetics of A Nigerian Tantalite Ore in …

& 0183;& 32;The results obtained as seen in fig.2, showed that the rate of tantalite ore dissolution is affected directly by the hydrogen ion H concentration. This agrees with previous grades 8, 20-22 . This is true up till 8.06M HNO3 after which there was a decline in the amount of the ore dissolved. Therefore, the optimum concentration of HNO3 that favours the dissolution is put at 8.06M, which was used for further studies.
