Composition of Ta- and Nb-ores and concentrates mainly used for processing; Main steps ofmodern processing; quality ofTa and Nb in metals, oxides and Gravity Process. The primary tantalum and niobium ore mainly adopt stage grinding and multi-stage gravity separation. Separation equipment is usually added to the grinding circuit to recover individual minerals in advance. Due to the better dissociation of the mineral monomer, the tantalum-niobium placer generally does not need crushing andNiobium-tantalum Beneficiation: How to Separate Niobium-tantalum Ore

Niobium and tantalum primary minerals are naturally occurring complex oxide ores, majorly of low grade deposits with chemical content of mainly Nb 2 /Ta 2 O 5 and oxides of Fe, Mn, Sn, Ti and other metal oxides. Over the decades, researchers have extensively and consistently investigated the extraction and recovery of Nb and Ta from These minerals are a combination of tantalum and niobium oxides. In fact, niobium is always associated with tantalum due to their chemical similarities [16, 44]. Moreover, the association of chemically similar niobium along with tantalum ore makes the primary extraction process very difficult and demands a tremendous amount of energy Global market trends of tantalum and recycling methods from

Lenticular output, the ore types are mainly earthy and semi-loose, and the cassiterite content is generally between 0.10kg/m3-0.8kg/m3, often accompanied by W, Nb, Ta, Ti, etc. In this deposit mining in Nigeria, the surface ore body has an exposed length of about 3000 meters, a width that ranges from 50 to 300 meters, and an average width ofThe chemical formula of niobium-iron ore-tantalite is AB2O6, both of which are referred to as niobium-tantalum. Where A in the formula stands for iron and manganese, and B stands for niobium and tantalum. The magnetization rate of niobium-iron ore-tantalite is (22.1 to 37.2) × 10-6.
