Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues.

Jun 14, 2018· Tantalum minerals contain 12 to 84 percent tantalum pentoxide; however, tantalum ores are low grade and contain only 0.01 to 1 percent tantalum pentoxide, which is equivalent to 0.1 to 10 kilograms per metric ton. As a result, to produce concentrates of tantalum, tantalite ore must be separated from other minerals in the ore.
Looking For Mining Investors. Our target is to produce twenty to thirty metric tons of tin Ore concentrate of 65-75% min in a month for a start. A geological survey of two and a half square kilometerhas revealed an estimated total reserve of Tin Ore (Cassiterite) of over fouty thousand metric ton within the area.

Sep 19, 2018· The procedure was repeated through a roll setting of 1.6 mm and a 1.67-mm screen. The combined coarse mica from the three screens comprised 41% of the feed weight and contained 4.9% of the tantalum and 7.9% of the niobium. This lost tantalum and niobium was considered part of the mica lattice rather than unliberated material.
