Tantalite Crusher and Grinding Equipment. Tantalite is group name for minerals with the chemical formula (Fe,Mn) (Ta, Nb)2O6 and it is a brown black, almost completely black orthorhombic shape mineral. Tantalite is located mainly in granite pegmatites also it accumulates up in drifts and after that it's extracted as Ta ore.

As tantalum, tin and tungsten deposits are generally hard rock, and low grade (particularly tantalum), they are considerably more difficult to process than mineral sands. Mining is either open cut or underground and requires drilling and blasting. The broken rock then requires crushing and grinding to liberate the minerals prior to separation.

Tantalum ore has characteristically grades of about 0.03% Ta 2 O 5, generally as a co-product of cassiterite and other minerals. Note that because of facile overgrinding, metallurgical recovery of columbite by crushing and milling hard-rock ore is often as low as 50%. Tantalum is silvery grey, heavy and very hard but malleable and ductile.

Tantalum occurs naturally most frequently in the form of tantalite ore, which has the formula (Fe, Mn) [(Nb,Ta)O 3] 2. When the tantalum content predominates, the ore is referred to as tantalite. When more niobium than tantalum is present, it is known as columbite or niobite.

Sample C was tested using only the method that involved grinding of a middling product. While the amount of tin removed was quite high (78%), tantalum loss to the tin byproduct was somewhat more than desired (4.5%). The loss of tantalum to the tin byproduct was proportional to the amount of tin byproduct obtained.
