1) On the basis of detailed studies on columbite from the Suzhou granite, tantalite has been found for the first time in this granite.

2) We have interest to buy tantalite, Ta2O5, coltan, columbite in Uganda and East African region.

3) We are one of the biggest end user of tantalite and columbite . We need the ores at the long-term.

4) There is high tantalite grade for certain large scale granite - pegmatite pattern tantalite - columbite mine in our country.

5) We are one of the biggest end user of tantalite and columbite. We need the ores at the long-term. If you have the ores to sell, please contact us instantly.

6) The measurement indicates that the optimized performance can be achieved by three - element composite columbite precursor methods.

7) The processing mineralogy character for altered granite pattern tantalite - columbite ore and its processibility has been studied.
