Since niobium with certain rare elements such as uranium, thorium, rare earths, titanium, zirconium, tungsten, and common elements tin, calcium, similar crystal chemistry of iron, manganese nature, equivalents, and prone aliovalently isomorphous effect, resulting niobium There are more than 130 kinds of minerals, and the composition is complex. It is difficult to unify the mineral classification. It is more reasonable to use the chemical composition and crystal structure as the classification basis. According to this principle, the strontium minerals can be divided into eleven groups: strontium iron. mine - group tantalite, pyrochlore - microlite group, dilute black gold ore - dilute gold complex aromatic, aliphatic weight tantalite, niobium, tantalum, antimony, group aeschynite group, xenotime family of niobium, tantalum,铌 silicate mineral family.
Although there are many kinds of strontium minerals, due to the complex composition of minerals, it is difficult to separate and purify the industry, which limits the utilization value of many minerals. The cerium minerals with industrial value mainly include coltan, pyrochlore and brown peony. Antimony ore, black gold ore, easy to solve stone, ilmenite rutile, etc.
