An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and ...
Plan for the proposed Tantalite Valley ... Tantalite Ore will be processed before storing and transporting it to its clients. This facility will be an important asset for the Mine but also the country, as this would ensure that value addition (processing Tantalite Ore) is done locally before Ore is shipped out of the country. The second activity will be the reworking on an existing Waste Rock ...

· Highlights Tantalite ore was digested using molten ammonium bifluoride. Niobium and tantalum were extracted using octanol as extractant. Addition of H 2 SO 4 improves the separation of niobium and tantalum. Extraction with 2octanol is almost similar to extraction with 1octanol. Two and three stages were sufficient for the extraction of Ta and Nb respectively.
