PRESENT PROCESSING METHOD OF THE PLANT The raw ore is supplied to feed hopper by loader m3 from storage site The 125 mm size boulders are separated by bar screen at feed hopper and these boulders thrown away to waste site The under size 125 mm the ore enters in trammel scrubber by pressure water from feed hopper
·Tantalum is obtained through the processing and refining of its ore tantalite which is the mineral containing tantalum Tantalum mines mostly operate as open pits although some are underground The mining process includes blasting crushing and transporting the tantalite ore to commence the separation of tantalum
The extraction and refining of tantalum including the separation from niobium in these various tantalum containing mineral concentrates is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures
·The extraction of niobium and tantalum from two tantalum niobium ore materials obtained from Mozambique using a combination of magnetic separation acid leaching solvent extraction and ion
·Niobium and tantalum are mainly produced from columbite tantalite ores and 60% of their production is nowadays located in the Democratic Republic of Congo and Rwanda The concentration of supply the scarcity the wide range of use in all electronic devices and the expected future demand boosted by the clean and digital transition means that Nb and Ta have

·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 and Nb remain a
·However these impurities tend to increase extraction cost and the level of difficulty in extracting Nb from the ore minerals Green extraction of niobium and tantalum from Kenticha tantalite ore using 1 ethyl 3 methyl imidazolium chloride ionic liquid J Min Environ 9 4 2018 pp 785 794 Google Scholar [52]
